Beta(-)-Delayed And Isomer Spectroscopy Of Neutron-Rich Ta And W Isotopes

摘要: Decays of neutron-rich A similar to 190 nuclei have been studied following projectile fragmentation a Pb-208 beam on Be-9 target at the GSI Fragment Separator. Gamma-ray decays from previously reported isomeric states in Ta-188, W-190 and (192,193) Re were used as internal calibrations for particle identification analysis, together with unreported Ta-189 W-191. The current work also identifies beta-delayed gamma rays decay Ta-188 W-188 first time.
