The study of Gamow Teller transition properties in 60-80 krypton isotopes by Pyatov method

In this study, Beta+ and Beta- Gamow Teller transition strength distributions and total B(GT) values for spherical even-even Kr isotopes in the mass region of 60-80 have been calculated by using Pyatov method and considering particle-hole interactions within pn-QRPA framework. According to the calculation results, GT fragmentation is felt more pronouncent in both B(GT)- and B(GT)+ strength distributions of 76-80 Kr isotopes. Moreover, it has been seen that the GT 1+ states in B(GT)- strength distributions shifts to higher energies as it is gone from 72Kr isotopes to 80Kr isotopes. It has also been observed that the structure in B(GT)+ strength distributions obtained for Kr isotopes in mass region of 72-78 is aggrement with those obtained by P. Sarriguren at all for oblate, prolate and spherical shapes of nucleus. It has been seen that our calculated total B(GT)+ values in 72-78 mass region are closer to those obtained by P. Sarriguren at all using SG2 Skyrme interaction within RPA framework.
