\delta(E2/M1) Mixing Ratios For Some Even-Even Tungston Isotopes and Rotational Limit

Authors: Salim ORAK

Abstract: Low-lying level study of even-even Wolfram is made by the use of IBM-I. It's found that these low-lying levels have rotational natural which corresponds to SU(3) limit of IBM-1. \delta(E2/M1) multipole mixing ratios of transitions in ^{182,184,186}W nuclei are also calculated via IBM-1 with SU(3) symmetry limit. Agreement of calculated values with experimental results are found. It's also possible to extend this method to calculate the other physical concepts belong to these nuclei.
