“…Evidences of large prolate deformations have also been found for 78980Sr from lifetime measurements (Lister etal 1982, Davies et al 1987, Heese et al 1990 and from many other experimental results (Theisen et al 1982, Ramayya el al 1988, Gross et al 1989. 82Sr has been studied by Haskins et al (1985) and Baktash et al (1991). Using the technique of atom-photon laser spectroscopy, Eastham et al (1987) have extracted the quadrupole deformation of proton-rich strontium isotopes.…”

The SVUCIW of the collective bands of 76~78~80~82Sr are studied within OUT deformed configuration mixing shell model based on Hme-Fock states. The self-conjugate nucleus 76Sr is found to be most deformed in the mass A = 80 region in agreement with experiment. The defamation is found 10 decrease for heavier isotopes. The calculated positive and negative parity bands agree quite well with experiment. The calculated B(E2) values are compared with the available expenmental mults. The agreement is quite satisfactory.

“…This signifies a shape transition from a deformed rotor at N = 38 to a spherical vibrator at N = 46, 48. Earlier studies have suggested that the energy level spacing for the ground state bands of 82 Sr show a vibrational like behavior and higher spins showing rotational structures [43]. But, Sr 80,82…”

The proton neutron interacting boson model (IBM-2) has been used to make a systematic study of Strontium isotopes in this mass region of A ∼ 80 with 38 ⩽ N ⩽ 48 and Z = 38. The three-term Talmi-Otsuka general Hamiltonian in the framework of the neutron proton version of the Interaction boson model was used to perform the calculations. The yrast levels energy are reproduced. The beta and gamma band energy levels also matched well. The reduced transition probabilities were also calculated and were found to be in agreement with the experimental values. In addition, g-factor for the 2 1 + state was evaluated. Possible candidates for mixed symmetry states were also predicted for several nuclei in this isotopic chain.

“…Gamma-ray spectroscopy continues to give new insight into the nuclear structure and remains a topic of interest over the decades [1][2][3][4][5]. The High Purity Germanium (HPGe) detector, having very good energy resolution is a powerful instrument for discrete γ-ray spectroscopy and remains the best apparatus for nuclear structure and astrophysics studies by making of HPGe array [6][7][8][9][10][11].…”

An active collimator has been designed to replace the heavy metal collimator of the BGO anti-Compton shield to improve the performance of the hybrid Indian National Gamma Array (INGA) at TIFR, Mumbai. The active collimators of the 24 clover detectors, along with the BGO anti-Compton shields and 18 LaBr3(Ce) detectors, can act as a γ-ray multiplicity filter. This configuration will be beneficial for studying weak band structures decaying by high γ-ray multiplicity events. In addition, the energy deposited in all the detectors can be added to get the sum energy for certain measurements aiming to use the hybrid array for calorimetric application. We have characterized an active collimator coupled with one of the anti-Compton shields and an HPGe clover detector with various radioactive sources. The peak-to-total ratio for the active collimator configuration is similar to the standard design with the heavy metal configuration with the 60Co source. Additionally, we have evaluated the Compton cross-talk between the clover HPGe detector and the anti-Compton shield/active collimator. The total multiplicity distribution for a cascade of eleven γ-rays with an energy range of 702000 keV has been obtained through GEANT4 simulation. The simulation results indicate the possibility of conducting a meaningful study of decay chains with a multiplicity of twelve.
