2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/217069We present Shell Model Monte Carlo calculations for nuclei within the full major shell 50-82 for both protons and neutrons. The interaction is determined solely by self-consistency and odd-even mass differences. The methods are illustrated for ${}^{124}$Sn, ${}^{128}$Te and ${}^{124}$Xe. We calculate shape distributions, moments of inertia and pairing correlations as functions of temperature and angular velocity. Our calculations are the first microscopic evidence of $γ$-softness of nuclei in this region.uuencoded postscript of manuscript with three figuresNuclear Theorytext
