Excited states of the [ital Z]=61 isotopes [sup 144]Pm[sub 83] and [sup 154]Pm[sub 84] have been studied in the [sup 19]F+[sup 130]Te reaction at a beam energy of 85 MeV. Gamma-ray and conversion electron spectroscopy were used to establish the high spin states of [sup 144]Pm up to spin 20[h bar] and to extend the level spectrum of [sup 145]Pm up to a tentative spin of 33/2[h bar]. Empirical shell model calculations in a configuration space truncated to the [pi]1[ital h][sub 11/2], [pi]1[ital g][sub 7/2][sup [minus]1], and [pi]2[ital d][sub 5/2][sup [minus]1] protons and the [nu]2[ital f][sub 7/2] neutron outside the [sup 146]Gd core reproduce the observed energy levels in good agreement with the experimental results. ([pi][ital h][sub 11/2])[sup 2] configurations are suggested in an [ital N]=83 isotone for [ital Z][lt]64.
