An IBM-2 Calculation of E2/M1 Multipole Mixing Ratios of Transitions in 90-96Sr

摘要

The interacting boson model is applied to the even strontium isotopes, 90-96Sr. Excitation energies, electromagnetic transition strengths, quadrupole and δ(E2/M1) multipole mixing ratios have been described systematically. It is seen that the properties of low-lying levels in these isotopes, for which the comparison between experiment and theory is possible, can be epistemologically satisfied by the Interacting Boson Model-2 (IBM-2).
