Gamow - Teller Strength in the P + Decay of 3 Ca 17 AUGUST 1992

B. Alex Brown iVational Superconducting Cyclotron Laboratory and Department of Physics and AstronomyM, ichigan State University, East Lansing, Michigan 48824-1321 (Received 18 February 1992) Calculations are presented for the Gamow-Teller strength distribution in the P+ decay of "Ca and compared to results extracted from recent beta decay data and from (p,n) data on the analog nucleus Cl. The strength distribution is shown to be sensitive to the Hamiltonian, and comparison with experiment indicates a need for further improvement in the ls0d shell Hamiltonian. It also indicates that the quenching of the Gamow-Teller operator in the upper part of the lsOd shell is similar to that deduced from previous analyses.
