Abstract : New decay data for the isotopes 259Sg and 255Rf were obtained at the velocity filter SHIP using an α-decay spectroscopy
measurement. Both isotopes were produced and studied via a one neutron evaporation channel in the compound fusion reaction
54Cr+208Pb. New isomeric states were observed and the single-particle level systematics for isotones with 151 and 153 neutrons
were extended. A change of the ground-state configuration for the heaviest N = 151 isotones was observed. Detailed Monte-Carlo
simulation for the α decay of 259Sg applying the Geant4 toolkit was performed and compared with experimental data.
