Abstract
High-spin states of the mass A = 39 mirror pair K-39 and Ca-39 were investi gated via the fusion-evaporation reaction Si-28+O-16 at 125 MeV beam energy . The GAMMASPHERE array in conjunction with the 4 pi charged-particle detec tor array MICROBALL and neutron detectors was used to detect gamma rays in coincidence with evaporated light particles. The results of the first high- spin study of the T-z = -1/2 nucleus Ca-39 are discussed in terms of mirror symmetry and compared to spherical shell-model calculations in the 1d(3/2) -1f(7/2) configuration space.
