High-spin members of the 4p-4h triaxial band in 40Ca

Research output: Contribution to journalArticlepeer-review


The states of 40Ca are described as mixtures of triaxial deformed intrinsic states. The few adjustable parameters are chosen to give good agreement for the low-lying energy levels. It is then found that the model can reproduce the energies of the high-spin states seen in heavy-ion scattering experiments at 9.9 MeV (8+) and 12.4 MeV (10+). The deviation of the energies of these states from the simple J(J+1)fs pattern can be explained as due to K-band mixing. Additional high-spin states are predicted at 15.8 MeV (12+) and 19.6 MeV (14+). Electromagnetic transition rates and other observables are generally in good agreement with experimental values.
