Effect of complex configurations on the description of properties of [sup.132]Sn beta decay

Gamow--Teller transitions in the beta decay of the [sup.132]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....

Zusammenfassung:Gamow--Teller transitions in the beta decay of the [sup.132]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 to 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 [sup.132]Sn half-life with respect to beta decay was obtained.
