Excited states ofTc fromMo( p,nγ)Tc reaction and the parabolic rule.

γ-spectra and excitation functions of theMo( p, nγ)Tc reaction were measured in the 1.2-3.6 MeV proton energy range by using thick, enriched targets, Ge(Li) and low energy photon (hyperpure Ge) spectrometers. These detectors were used in γγ-coincidence experiments, too. Conversion electron spectrum measurements were performed by means of a superconducting magnet transporter Si(Li) spectrometer (SMS) at E =4 MeV and multipolarities of some transitions have been determined. Based on the experimental results a level scheme ofTc has been constructed. Level energies ofTc were calculated on the basis of the parabolic rule, derived from the cluster-vibration model.
