Abstract: | New possibilities for phonon-structure investigations in even-even nonspherical nuclei have been found. The multipole-mixing
parameters δ for E2 + M1 transitions from β-and γ-rotational bands to ground-state rotational band are used. The new possibilities are based on the relationship of the negative
sign of δ with negative magnetic momentum of some neutron Nilsson states, invariability of δ sign for γ transitions between rotational bands, and enlarged probabilities for M1 transitions only in the presence of certain two-quasiparticle configurations in initial and final states.
