| 摘 要： | The beyond mean-field approach for low-lying hypernuclear states is extended by mixing the confgurations associated with both single-particle and quadrupole-octupole collective excitations within the generator coordinate method based on a covariant density functional theory. The method is demonstrated in the application to the low-lying states of 21ΛNe, where the confgurations with the Λ hyperon occupying the frst(Λs) and second(Λp) lowest-energy state...
