Description

The level scheme of the doubly odd nucleus 146Pm was investigated by means of in-beam spectroscopy. The 146Nd(p, n) reaction in the 3.5-8 MeV proton energy interval on enriched targets has been used to populate the exited states of 146Pbm. High resolution γ-ray spectra using Ge(Li) and hyperpure Ge detectors and conversion electrons with a mini-orange spectrometer were measured. With γ-exitation functions and nγ-coindidences using nγ-discriminated NE231 neutron detectors transitions in 146Pm were identified. γγ-coincidences gave information about γ-cascades. With these data a level scheme of 38 levels below 1.1 MeV exitation energy has been deduced including 73 transitions. For 12 transitions experimental conversion coefficients have been evaluated, which agree with the expected values for M1/E2-transitions. (orig.)
