We discuss systematics of the {ital M}1 scissors mode within the interacting boson model when the {ital g}-boson degree of freedom is included explicitly and microscopically motivated choices of model parameters are adopted. We try to relate the {ital M}1 centroid energy to the energetics of deformation. We conclude that, with the introduction of a hexadecapole-hexadecapole interaction and a {ital g}-boson admixture in the ground state of only a few percent, we can obtain reasonable estimates of the {ital M}1 centroid energy, without invoking a Majorana interaction. If one takes seriously variations in microscopic estimates of boson {ital g} factors, then the summed {ital M}1 strength near midshell can be interpreted in terms of boson occupation numbers which saturate. {copyright} {ital 1996 The American Physical Society.}
