Magnetic rotational band in Sb-116

The excited states of Sb-116 have been populated using the alpha induced reaction In-115(alpha, 3n)Sb-116 at a beam energy of 40 MeV and investigated via in-beam gamma spectroscopic techniques. A positive parity sequence (B1) of strong M1 transitions with relatively weak crossover E2 transitions, connected to the yrast negative parity rotational band (B2) of Sb-116, has been observed. The experimental B(M1)/B(E2) values for band B1 are found to decrease with angular momentum (I). The origin of this band (B1) has been interpreted in terms of Magnetic Rotation (MR) under the framework of Semi-Classical Model (SCM) and Shears mechanism with Principal Axis Cranking (SPAC) formalism and is assigned a four quasiparticle configuration of pi (g9/2)(-1) circle times nu(g(7/2)/d(5/2))(h(11/2))(2). The yrast rotational band B2 is extended up to the band crossing region.& nbsp;(C) 2022 Elsevier B.V. All rights reserved.
