Decay Spectroscopy at SHIP using the COMPASS set-up — •A. K. Mistry for the SHIP Decay Spectroscopy collaboration — Helmholtz Institut Mainz, Mainz, Germany — GSI Helmholtzzentrum, Darmstadt, Germany

A vital tool in the study of the structure of the nucleus is experimental decay spectroscopy in the focal plane after online separation of reaction products. In the heavy element region of the nuclear chart, a variety of theoretical models predict location of the enhanced shell stabilization region above the spherical closure at 208Pb (Z=82, N=126). Studies on the properties of nuclei at the edges of this enhanced superheavy region constrain these models by examining the evolution of shell closures in experimentally accessible regions of the nuclear landscape . Whilst current understanding of the spherical shell closures up to 208Pb is well established, towards the proton dripline, experimental knowledge on the evolution of the shell closures remains limited. To this end, recent efforts have focused on examining the N=126 shell closure at extreme proton numbers i.e. Z=92. The new focal plane detection system at SHIP COMPAct decay Spectroscopy Setup (COMPASS) was employed during a period of parasitic beam time at GSI, with the two-fold purpose of performing an advanced commissioning of the setup, and to subsequently produce neutron deficient isotopes around the region of U, Np, and Pu. Results will be presented from the production of heavy, neutron deficient actinide isotopes with short lived decays in their corresponding chains.
