Nuclear Physics

In General > s.a. constants; nuclear technology [including fusion, weapons]; symmetry.
* History: 1939, Lise Meitner and her nephew Otto Frisch, during a Christmas Eve walk, come up with the idea of nuclear fission (the term was taken from cell biology) while discussing results by Otto Hahn and Fritz Strassmann in Berlin; 1949, Nuclear shell model proposed; 1950s, Clear idea of n's and p's in the nuclei; 2002, Traditional nuclear physics is "dying" (work is now around engineering applications), and the excitement in the field has moved toward its marriage with astrophysics and understanding of nucleosynthesis in the early universe and in stars, the motivation behind the push for building the RIA (rare-isotope accelerator).
* Models / calculations: The oldest model, still fundamentally fine but in practice difficult to calculate with, is the shell model; It can be used, starting with a mean-field approximation with corrections, up to A = 60; Beyond that, use a deformed basis, and apply "angular momentum projection" numerically.
* Magic numbers: The nuclear shell model explains that nuclei with certain magic numbers (2, 8, 20, 28, 50 and 82) of neutrons and/or protons are especially stable because the neutrons and/or protons form closed shells; Nuclei that contain magic numbers of both protons and neutrons are even more stable and are said to be "doubly magic".
* Half-lives: ¹⁴C, 5.730 yr; ²¹⁴Po, 10^–4 s; ²³⁹Pt, 24,000 yr.
