Decay Spectroscopy of Heavy Isotopes at SHIP Using the COMPASS Focal Plane Detection Set-up

The new COMPASS detection system designed and developed at GSI, Darmstadt was employed in the focal plane of the SHIP velocity filter online during a period of commissioning. The isotope No-254 was initially measured for control purposes, following which the nuclei, U-227,U-228,U-230, Np-229, and Pu-229,Pu-230 were synthesized. The obtained data from alpha-decay spectroscopy is evaluated and compared with previous measurements.
