Nuclear Structure Investigations Of Heavy Nuclei And The Decay Of SHE

Within the framework of our studies of proton rich nuclei around the N 126 and N = 152 neutron shells we have performed a series of α-γ-coincidence studies. The nuclei of interest were separated in-flight by the velocity filter SHIP and implanted into a position sensitive 16-strip PIPS-detector where their arrival and subsequent α-decays were registered. Associated γ-rays were detected by a Ge-Clover-detector. In the present work recent results concerning 216Th and α-decay chains of 251No and 257Db are given together with brief discussion
