摘要: All the available experimental evidence relating to statistical distribution of dense nuclear levels is collected together and analysed. The simplest adequate equation state U = (1/11)At2 - t + (1/8)A2/3t7/3 MeV which leads D0 0.11A2(U t)2exp[-{2(AU/11)1/2 (3/32)(11U)2/3}] for spacing zero angular momentum. significance these formulae discussed. An appendix refines theoretical level density formula a Fermi gas with fixed number particles; this analysis incidentally yields slightly more accurate form simple Hardy-Ramanujan asymptotic partitions positive integer.
