Abstract
γ-spectra and excitation functions of the100Mo(p, nγ)100Tc 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 inγγ-coincidence experiments, too. Conversion electron spectrum measurements were performed by means of a superconducting magnet transporter Si(Li) spectrometer (SMS) atE p =4 MeV and multipolarities of some transitions have been determined. Based on the experimental results a level scheme of100Tc has been constructed. Level energies of100Tc were calculated on the basis of the parabolic rule, derived from the cluster-vibration model.
