Wikimedia Commons Following Meitner's departure, the two friends and collaborators remained in close contact, communicating almost daily via letters. Seeking insight from Meitner, Hahn wrote to the exiled physicist in December of detailing neutron bombardment experiments in which he had surprisingly detected barium among the decay products. He described the process as the 'bursting' of the uranium atom. Over the Christmas holiday, the two theoretical physicists laid the foundation for the theory of nuclear fission by interpreting Hahn's experiments.

They described how the uranium nucleus could split into multiple smaller nuclei based on the existing liquid-drop model of an atomic nucleus. Meitner and Frisch's final interpretation elegantly integrated the pre-existing liquid-drop nucleus theory, settled misconceptions about transuranic elements as neutron bombardment products and provided quantitative energy predictions.

On January 6th,Hahn and Staussmann published their uranium splitting results in Die Naturwissenschaft, becoming the first to experimentally describe nuclear fission.

Lise Meitner's exclusion from the Chemistry Nobel Prize and subsequent failure to receive a Physics Nobel Prize has remained particularly controversial, especially given the fact that Meitner was nominated for a Nobel Prize a grand total of 48 times. On her side, Meitner publically supported Hahn's Nobel Prize achievement, emphasizing the significance of his experimental work and his deservingness of the prize.

Yet, she was bruised by the lack of recognition and stated in private letters that she and Otto Frisch deserved credit as well. More nefarious, Meitner's personal conflict with committee member Manne Siegbahn and negative personal sentiments of other members may have cost her the Nobel Prize in Physics.

For her extraordinary life work, Meitner did receive a number of awards, including the Max Planck Medal and the Enrico Fermi Prize, and the element Meitnerium was named in her honor.

Ina personal position was created for her at the University College of Stockholm with the salary of a professor and funding from the Council for Atomic Research.

On 15 Novemberthe Royal Swedish Academy of Sciences announced that Hahn had been awarded the Nobel Prize in Chemistry for "his discovery of the fission of heavy atomic nuclei.

There is really no doubt about it. But I believe that Otto Robert Frisch and I contributed something not insignificant to the clarification of the process of uranium fission—how it originates and that it produces so much energy and that was something very remote to Hahn. He would have deserved it even if he had not made this discovery. But everyone recognized that the splitting of the atomic nucleus merited a Nobel Prize. Both he and Meitner had been nominated for both the chemistry and the physics prizes several times even before the discovery of nuclear fission.

In the s, the long-sealed records of the Nobel Committee's proceedings became public, and the comprehensive biography of Meitner published in by Ruth Lewin Sime took advantage of this unsealing to reconsider Meitner's exclusion.

Meitner's exclusion from the chemistry award may well be summarized as a mixture of disciplinary bias, political obtuseness, ignorance, and haste. Referring to the leading German nuclear physicist Werner Heisenbergshe said: Meitner's grave in Bramley You all worked for Nazi Germany.

And you tried to offer only a passive resistance. Certainly, to buy off your conscience you helped here and there a persecuted person, but millions of innocent human beings were allowed to be murdered without any kind of protest being uttered Also Hahn wrote in his memoirs, which were published shortly after his death inthat he and Meitner had remained lifelong close friends.

She became a Swedish citizen in She retired in and moved to the UK where most of her relatives were, although she continued working part-time and giving lectures. A strenuous trip to the United States in led to Meitner having a heart attackfrom which she spent several months recovering.

Her physical and mental condition weakened by atherosclerosisshe was unable to travel to the US to receive the Enrico Fermi prize. President Johnson sent Glenn Seaborgthe discoverer of plutonium, to present it to her.

The presentation was made in the home of Max Perutz in Cambridge. After breaking her hip in a fall and suffering several small strokes inMeitner made a partial recovery, but eventually was weakened to the point where she moved into a Cambridge nursing home. She died in her sleep on 27 October at the age of July or his wife Edith, as her family believed it would be too much for someone so frail.

James parish church, close to her younger brother Walter, who had died in Her nephew Frisch composed the inscription on her headstone. She lectured at PrincetonHarvard and other US universities, and was awarded a number of honorary doctorates. She was nominated by Otto Hahn for both honours. Meitner's name was submitted, also by Hahn, to the Nobel Prize committee more than ten times, but she was not accepted. Meitner was elected a foreign member of the Royal Swedish Academy of Sciences inand had her status changed to that of a Swedish member in Hahn wrote to Meitner: They scribbled formulas on a scrap of paper in the woods: Hahn, however, continued to maintain that he was the sole discoverer of fission, through accepting the Nobel Prize in and for the rest of his life.

No, said Lise Meitner; Hahn was too good a chemist for that. But how could barium be formed from uranium?
