Isomeric states in the light Tc isotopes

Preliminary results from the first experiment of the Stopped Beam RISING campaign are presented. The relativistic projectile fragmentation of a 750 MeV/u beam of 107Ag populated isomeric states in very neutron deficient nuclei at the proton dripline around mass 80–90. Nuclei were unambiguously identified using the FRagment Separator (FRS) and its an- cillary detectors located at GSI. The ions produced were slowed down from relativistic energies by means of an Al degrader and implanted in the centre of the high-efficiency Stopped RISING array. This allowed the identifica- tion of new excited states in the N = Z = 43 nucleus, 86Tc, populated following the de-excitation of a microsecond isomer. Preliminary results of this analysis, as well as previously unobserved isomeric states in 87,88Tc, are reported
