Intermediate bands structure of the ¹³⁴Ba nucleus

In the present work, the ¹³⁴Ba nucleus was populated using the reaction ¹²⁴Sn(¹³C, 3n)¹³⁴Ba at a beam energy of 48 MeV from the Pelletron accelerator at Tata Institute of Fundamental Research (TIFR), Mumbai. The ¹²⁴ Sn target of thickness 1.5 mg/cm² with the Au backing was used. The gamma-rays were detected using the Indian National Gamma Array (INGA). The clover detectors were arranged at different angles with 3, 3, 1 and 4 clovers are placed at 157°, 140°, 115° and 90° with respect to the beam direction, respectively. In the present study, the level scheme was extended upto a maximum spin of 20ħ. The spin and parity of the levels were assigned using the angular distribution, R_DCO and polarization measurements. In the intermediate excitation, three quadrupole bands were observed and the level of the gamma-band was re-confirmed at the low-excitation. The theoretical calculations to understand these bands are in progress
