Abstract
Excited states of the Po-203 (Z = 84, N = 119) have been investigated after populating them through Pt-194(C-13, 4n) fusion-evaporation reaction at E-beam = 74 MeV and using a large array of Compton-suppressed HPGe clover detectors as the detection setup for the emitted ?? rays. Standard techniques of gamma-ray spectroscopy have been applied towards establishing the level structure of the nucleus. Twenty five new gamma-ray transitions have been identified therein, through gamma-gamma coincidence measurements, and spin-parity assignments of several states have been determined or confirmed, following the angular correlation and linear polarization measurements on the observed gamma rays. The excited states have been interpreted in the framework of large basis shell-model calculations, while comparing their calculated and experimental energies. They have been principally ascribed to proton population in the h(9/2) and i(13/2) orbitals outside the Z = 82 closure and neutron occupation of the f(5/2), p(3/2), and i(13/2) orbitals in the N = 126 shell.
