Science and Education Publishing International Journal of Physics 2333-4576 4 1 2016 1 8 An IBM-2 Calculation of E2/M1 Multipole Mixing Ratios of Transitions in 90-96Sr 5 10 EN Saad Naji Abood Laith Ahmed Najim Department of Physics, College of Science, Mosul University, Mosul, IRAQ IJP2016412 10.12691/ijp-4-1-2 2015 9 12 2015 10 25 2016 1 6 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).
