Proton-neutron symmetry in low lying collective modes

Abstract

Properties of collective states which depend on the proton and neutron content of the nucleus are investigated in the frame work of the F-spin concept. Experimental evidence for F-spin as well as data on F-spin multiplets is given. “Global” descriptions of groups of nuclei in the Interacting Boson Model are discussed. F-spin forbidden M1 transitions are discussed and values for F-spin purity of the gamma band in 128Xe and 168Er are given.
