Abstract: The excited states of 116 Sb have been populated using the α induced reaction 115 In( α , 3n) 116 Sb 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 116 Sb, 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 π ( g 9 / 2 ) −1 ⊗ ν (g 7/2 /d 5/2 )(h 11/2 ) 2 . The yrast rotational band B2 is extended up to the band crossing region.

TL;DR: Researchers identify a low-K decoupled band and a high-K coupled band in 115Sb, providing evidence for prolate-oblate shape coexistence associated with g9/2 proton-hole configuration around Z=50 shell closure, supported by theoretical calculations.

Satya Samiran Nayak,G. Mukherjee +1 more
TL;DR: A new software suite called BiNDAS has been developed, primarily using $\text{C}^{++}$ , for nuclear spectroscopy data sorting and analysis, and is expected to significantly reduce data analysis time, while keeping human errors to a minimum.

ESCL8R and LEVIT8R: Software for interactive graphical analysis of HPGe coincidence data sets
TL;DR: In this article, a level scheme is proposed to calculate an expected spectrum for comparison with the observed spectrum, and a graphics-based editor is included to allow fast and easy modification of the proposed level scheme, and least-squares fits to the matrix or cube can be performed to extract optimum values for the energies and intensities of the level scheme transitions.
Electromagnetic radiation of rotating nuclei
TL;DR: In this paper, an intrinsic representation of the radiative multipole operators is derived, which enables one to calculate directly electromagnetic transition amplitudes with cranking states, in this way both the orientation of the intrinsic system in space and the structure of the quasiparticles can be properly taken into account.
