Charge-exchange Resonances of Tin Isotopes in Sn(3He,t)Sb Reaction
Abstract
Charge-exchange resonances: the giant Gamow–Teller, analog and the so-called “pygmy” resonances have been studied in the self-consistent theory of finite Fermi systems. Microscopic and semi-classical calculations are presented for nine tin isotopes with known experimental data 112,114,116,117,118,119,120,122,124Sn. These data is from Sn(3He,t)Sb charge-exchange reaction at the energy (3He) = 200 MeV. The average standard deviation for GTR and AR energies is δE ≤ 0.30 MeV that is close to the experimental E
