Investigation Of The Magnetic Dipole Moments Of The IπK = 1+1 States In The Even-Even Deformed Nuclei

This study focuses on the investigation of the magnetic dipole moments of the excited IπK = 1+1 states in the even-even deformed nuclei in the framework of the Quasi-particle Random Phase Approximation (QRPA). An analytic expression for the magnetic dipole moments of the states known to be generated by the isovector spin-spin forces is obtained. Using this analytic expression, the magnetic moments of the low-lying 1+ states for the 148,150Ce and 150,152Nd isotopes are also calculated numerically in the spectroscopic energy region. Furthermore, the reduced transition probabilities B(M1) and the lifetimes for each 1+ state are given
