Abstract
Microscopic analysis of recent data on beta-decay of even neutron-deficient nuclides between Sn-100 and Sn-108 is performed within the self-consistent finite Fermi-system theory and BCS plus Quasiparticle Random Phase Approxi mation with G-matrix interaction and proton-neutron pairing. Strength funct ions of Gamow-Teller beta- decay are calculated. The mechanisms of reductio n of the GT strength are discussed.
