TL;DR: An improved version of the statistical tests of R Frosch Nuovo Cimento 52A, 677 (1967) is presented, and these tests are applied to the particle masses compiled by the Particle Data Group in the Reviews of Modern Physics as discussed by the authors.
Abstract: An improved version of the statistical tests of R Frosch Nuovo Cimento 52A, 677 (1967) is presented, and these tests are applied to the particle masses compiled by the Particle Data Group in the Reviews of Modern Physics. The mass formula under discussion is m/sub i/ = (N/sub i/ + x/sub i/)3m/sub e/, where m/ sub i/ is one of the 15 st able particle masses specified, N/sub i/ is an integer, and x/sub i/ is a small positive or negative number.

TL;DR: In this paper, the second-order mass formula of Okubo for the 3/2+ baryon resonances was derived for the unification of SO(6,1) as a spectrum generating algebra.
Abstract: The study of the unificationSO(6,1) as a spectrum generating algebra is continued to include baryons in the scheme. Among others, the second-order mass formula of Okubo for the 3/2+ baryon resonances is derived.
TL;DR: In this article, the authors used Myers and Swiatecki's mass formula and a phenomenological level density formula, originally developed by Gilbert and extended for deformed nuclei by the present authors, to calculate fission fragment distributions based on Fong's statistical theory.
Abstract: Calculation of fission fragment distributions based on Fong's statistical theory was carried out for the case of 241 Am thermal neutron fission using Myers and Swiatecki's mass formula and a phenomenological level density formula, originally developed by Gilbert and extended for deformed nuclei by the present authors. The results show that Fong's statistical theory with the now attainable knowledge on mass and level density, can only account for narrow asymmetric mass peaks centred around A ≃108 and 134. The present results are in good agreement with those calculated by Ignatyuk with a microscopic approach. Other physical quantities associated with fission reaction, such as, kinetic energy distribution, charge distribution and total excitation energy distribution at scission configuration are given. Comparison was also made among various approaches for level density formulation.
