TENSOR EFFECTS ON THE SPIN-DEPENDENT CHARGE-EXCHANGE TRANSITIONS

摘要

Effects of the tensor force on the Gamow-Teller (GT) and Charge-exchangeSpin-Dipole (SD) transitions in 208Pb and 90Zr are studied through selfconsistentHartree-Fock plus Random-Phase-Approximation (HF+RPA) theorybased on Skyrme force.It is found that tensor force produce strong effecton the GT and SD transitions.These strong effects can be good candidates toconstrain the strength of tensor force or choose Skyrme parameter sets whichincluded the tensor force.
