Description
The level structure of A~100 nuclei reveals intriguing phenomena even at low and moderate spin regimes such as vibrations and rotations built upon prolate deformed states [1,2,3]. The underlying configurations present a favourable condition for the possible observation of wobbling, even at low spins [4]. The aforementioned features provided the necessary impetus for us to revisit the level structure of 103Pd, especially at moderate angular momentum spins. Hence, the 94Zr(13C, 4n) reaction at an incident energy ~ 55 MeV was employed to populate the high spin states in 103Pd. The 94Zr target was ~ 1mg/cm2 thick with ~ 10 mg/cm2 gold backing. The de-exciting gamma transitions were detected using the Indian National Gamma Array (INGA) then stationed at IUAC,New Delhi. The detectors placed at angles of 32°, 57°, 90°,123° and 148° with respect to the beam direction.
| Summary | The preliminary analysis has confirmed all the earlier reported transitions belonging to this nucleus. About five new transitions have been observed and are being placed in the level scheme. The use of clover detectors would allow us to undertake the linear polarization measurements which when coupled with the observed angular intensity anisotropy would help us unambigiously assign the electromagnetic nature to the observed transitions. The earlier reported measurements would help us to benchmark the current methodology. The observation of Doppler affected gamma rays (as the emission occurs during the slowing down of the recoils) would facilitate the level lifetime measurements using the conventional DSAM. It is expected that a collation of these experimental observables will help us to develop a detailed level structure of 103Pd and provide an insight into the underlying microscopic configurations. |
