Experimental study of nuclei in the vicinity of 'island of inversion' through the fusion reaction

As a part of our on-going programme we have investigated the level structures of 32,33,34P and 32,33S, using 18O (18O, xnyp) and 18O (16O, xnyp) reactions at an incident beam energy of about 34 MeV. The de-exciting gamma-transitions were recorded using an array of clover detectors. These detectors have a dual advantage of higher efficiency at Eγ ≥ 2 MeV, and are capable of providing information on the linear polarization of the observed γ-transitions. These polarization measurements when coupled with the angular correlations help us assign uniquely the spin-parity for the observed levels. The level structures of these nuclei have been substantially extended due to the observations of several new transitions
