Chapter 137: Found fission

　　 "General Cyric, the direction you specified is indeed correct!" At this time, in an office at the University of Berlin, several people were very excited. They wore glasses and looked like a full-fledged scholar!
　　 Now, it is Hahn, one of the most famous chemists in Germany, who is over fifty years old this year, his hair is beginning to turn white, and he is in good spirits.
　　 As a scientist, what I want most is to win a Nobel Prize, and now, Hahn seems to have seen the Nobel Prize beckoning to him!
　　 Of course, not only Hahn, but also his assistant, Strassman, also contributed to this discovery!
　　What found? The most significant discovery of the 20th century! Fission of the nucleus!
　　In history, this was an accidental discovery.
　　 Historically, in 1938, the scientific community had made such a discovery that uranium produced some beta radionuclides after neutron irradiation, but many scientists believed that this was a transuranium element.
　　 There are only two people, Hahn and Strassmann. After carefully identifying the nuclear reaction products, it is certain that one of them is radioactive barium. What does this indicate? The uranium nucleus fissioned and became a new nucleus!
　　In Einstein's theory, the fission of atomic nuclei will be accompanied by loss of mass and release of energy!
　　 For this contribution, Hahn won the Nobel Prize in Chemistry in 1944!
　　 And now, two years earlier than in history, they have made this discovery! Thanks to a meeting held by Cyric for these scientists half a year ago!
　　 At the meeting, Cyric explained his emphasis on nuclear physics and pointed out some directions.
　　 However, many people disagree with Cyric's words.
　　 When did a soldier come to intervene in the scientific world, boy, do you know how the nucleus is made up?
　　 Many people have prejudices against Cyric. After all, Cyric has no prestige in the scientific community.
　　 Only Hahn listened, took his assistant and did a lot of experiments. Finally, he confirmed that Cyric's statement was correct. Bombarding the uranium nucleus with slow neutrons can fission!
　　 This is a discovery that shocked the entire scientific community!
　　 Cyric was called out late at night, for this reason, at this time, almost all German nuclear physics experts arrived!
"First of all, I congratulate the two for their amazing discoveries." Cyric rubbed his eyes, and said to Hahn and his assistants who were beaming: "At the same time, for the sake of Germany, I hope you can protect your discovery for the time being. , Cannot be published publicly yet."
　　 "Why?" Hahn was stunned.
"For Germany." Cyric said: "I believe everyone knows what this discovery means. Atomic nuclei can be fissioned and can release a lot of energy. If these energy are released smoothly, then It will bring convenience to our lives, for example, it can become a source of electricity, and if it is released violently in a short period of time, it is a weapon."
　　How did the United States begin to study nuclear weapons in later generations? At first, it was discovered that all academic papers on nuclear physics disappeared. As a result, the guys like Einstein couldn't sit still. They realized that Germany might be studying nuclear weapons!
　　 Therefore, they wrote to Roosevelt and asked to study nuclear bombs secretly. As a result, Germany gave up and the United States succeeded.
　　 And now is the first moment. For example, even the fission of the atomic nucleus has not been discovered yet. If we keep this secret from now on, then Einstein and others will not notice anything.
　　Germany, from now on, develop secretly!
"We have endured for more than ten years, and we will never continue to endure." Cyric said: "Maybe you are not interested in politics, but I want to say that only if Germany is strong can we have a future. If other countries, such as the United Kingdom and the United States, succeed in manufacturing such atomic weapons, then it will be our end."
Cyrenk from later generations, of course, knows a lot. There are many reasons why Germany failed to develop the atomic bomb. The passive sabotage of these scientists in front of them must be regarded as one aspect. The wrong research direction is another aspect. .
　　 And now, they must not be allowed to continue the old path!
"Our current research has two goals. In peacetime, nuclear energy can be released steadily to serve our country and people. When in wartime, let it become a Spartakley sword hanging high above the enemy! Cyric continued: "Everyone present is a hero of Germany. Although you will be silent now, your deeds will be written into our textbooks and become well-known heroes in the future."
　　 "I have always believed that it is not politicians but scientists who change history!" Cyrek continued: "Science is the driving force for the development of this world, and we have opened the door to the use of atomic energy!"
　　Incitation~EbookFREE.me~ with instigation, Cyric hopes that his painstaking efforts will be effective.
"General Cyrek, don't be too optimistic." At this moment, the famous scientist Heisenberg, a veteran of the German scientific community, said: "Now, only the fission of the uranium nucleus is observed in the laboratory. There is still a long way to go before practical applications."
At this time, Heisenberg had put away his previous contempt, and solemnly explained to Cyric: "First, we need a large amount of uranium raw materials. In nature, uranium ore contains the highest content of uranium 238, and uranium 235 is not To one percent, and our experiments proved that only uranium-235 can split."
　　If it was before, Heisenberg would never talk nonsense with Cyric, but now, since Cyric's correctness has been confirmed, Heisenberg will treat Cyric as a person in the scientific community to communicate.
　　Whether you want to build a nuclear reactor or a nuclear bomb, you need the purity of the nuclear raw materials to be high enough, and it is not so easy to enrich uranium 235 in uranium ore.
　　In later generations, if you want to use uranium for nuclear bombs, you need a centrifuge, which is to enrich uranium-235. This method has huge investment and poor results.
"Yes, this is a problem, but this problem is actually very easy to solve." Cyric took a piece of chalk in his hand, and on the small blackboard on the side, he wrote that a later high school student would write The nuclear reaction equation: "Uranium 238 cannot be split, but when it captures neutrons, it can become plutonium 239, plutonium 239, which is easy to fission."
　　 In contrast, making plutonium bombs is much easier than uranium bombs! Because this method no longer needs a centrifuge, just keep burning in the reactor to burn the uranium into plutonium, that's it!
