Using the principle of additivity, the quasi-particle contribution to magnetism in high-K isomers of Lu - Re has been estimated. Based on these estimates band structure branching ratio data is used to explore the behavior of the collective contribution as the number and neutron/proton nature (Np, Nn), of the quasi-particle excitations, change. A striking systematic variation of the collective g-factor gR with the difference, Np – Nn, is revealed. Basic ideas of pairing, its quenching by quasi-particle excitation and the consequent changes to moment of inertia and collective magnetism are discussed. The new found systematic behaviour of gR opens a fresh window on these effects amenable to detailed theoretical investigation.
