The isovector parts are predicted to be around 0.15, and the proton effective charges are around 1.25 e, which is less than the empirical value of epff p = 1.5 e. The microscopic effective charges in neutron rich 51Mn are about 10% less than its proton rich mirror. These effective charges are combined with the shell model to calculate the reduced electric quadrupole transition probability B（E2） values in 51Mn and 51Fe. It turns out that the microscopic effective charges have well reproduced the B（E2） values and its ratio in the terminating states.展开更多

The level scheme of 141Nd has been extended up to an excitation energy of 7614.5 kev including 12 new γ rays deexciting 15 new levels. According to particle-vibrator coupling and semi-empirical shell model calculations, the level structure of 141Nd can be well interpreted by coupling an h11/2 neutron-hole to the respective excited states in 142Nd core.展开更多
