- Abstract
Gamow-Teller transitions in the beta decay of the Sn neutron-rich nucleus was described microscopically. The coupling of one- and two-phonon components of the wave functions was taken into account on the basis of Skyrme interactions featuring various contributions of the tensor component. A separable approximation of the particle-hole interaction made it possible tohole interaction perform calculations in a large configuration space. It was shown that an increase in the strength of the neutron-proton tensor interaction led to an increase in the energy of Gamow-Teller transitions. In addition, a decrease in the Sn half-life with respect to beta decay was obtained.
