Abstract.
A systematic shell model description of the experimental Gamow-Teller transition strength distributions in 42Ti , 46Cr , 50Fe and 54Ni is presented. These transitions have been recently measured via \(\beta\) -decay of these \( T_z=-1\) nuclei, produced in fragmentation reactions at GSI and also with (3He, t) charge-exchange (CE) reactions corresponding to \( T_z=+1\) to \( T_z=0\) carried out at RCNP-Osaka. The calculations are performed in the pf model space, using the GXPF1a and KB3G effective interactions. Qualitative agreement is obtained for the individual transitions, while the calculated summed transition strengths closely reproduce the observed ones.
