Coriolis coupling effects in proton-pickup spectroscopic factors from B 12

摘要: Spectroscopic factors to low-lying negative-parity states in extracted from the proton-removal reaction are interpreted within the rotational model. Earlier predictions of the -wave proton-removal strengths in the strong-coupling limit of the Nilsson model underestimated the spectroscopic factors to the and states and suggested that deviations in the ground state of the odd-odd due to Coriolis coupling should be further explored. In this work we use the particle rotor model to take into account these effects and obtain a good description of the level scheme in , with a moderate mixing of the proton Nilsson levels [110]1/2 and [101]3/2. This mixing, present in the bandhead of , is key to explaining the proton-pickup data.
