Description

The high spin states of neutron-rich 106,107Tc nuclei have been reinvestigated by observing prompt γ rays from the spontaneous fission of 252Cf. In 106Tc, a previously known collective band is expanded, and a new collective band is identified. In 107Tc, a collective band based on the π5/2-[303] orbital is confirmed and extended. Inconsistencies in the configuration assignments for positive parity bands in 105,107Tc in the previous reports are clarified. The spins and parities as well as the configurations for the two bands in 106Tc are assigned according to the angular momentum alignments and g-factor calculations. Other characteristics for the observed bands are discussed.
