The high angular momentum structure of Pm141 has been studied via the Te126(19F,4n) reaction at beam energies from 74 to 84 MeV. In-beam -ray spectroscopy techniques, including -ray excitation function, - coincidence, and -ray angular distribution measurements were used. A level spectrum up to an excitation energy of 4782 keV was constructed. Definite parity assignments were made up to the (21/2- state. The low-lying structure is discussed in terms of a weak coupling between the valence proton and the N=80 cores. The earlier treatment of Pm141 in terms of a particle-plus-triaxial rotor is critiqued.
