摘要：

The purity of intrinsic states of nuclei with respect to a proton-neutron boson symmetry (F spin) is shown to be largely determined by the difference between proton and neutron deformations and not by whether the Hamiltonian is an F-spin scalar. Upper and lower bounds on F-spin mixing in the ground-state band of Ho165 are estimated using recent pion single-charge-exchange data. © 1990 The American Physical Society.
