[en] The level scheme of ¹⁵¹Pm populated by the β-decay of 12 min ¹⁵¹Nd has been studied using Ge(Li) detectors as singles and coincidence γ-ray spectrometers. Most of the new γ-rays have been included in a partial level scheme of ¹⁵¹Pm involving four new levels. Angular correlation measurements on the 170.752-255.678 keV and 170.752-138.882 keV cascades have been made with the result A₂=0.088+-0.005 and -0.02-+0.05, respectively. A PAC measurement on the 170.752-255.678 keV cascade has yielded the g-factor of the 255.676 keV level as g=1.18+-0.16. A Nilsson-model calculation including Coriolis coupling has been made and the experimental level energies have been well reproduced by the Nilsson orbitals [413](spin down), [411](spin up), [420](spin up), [532](spin up), [541](spin up), and [550](spin up). Theoretical transition rates, E2/M1 mixing ratios, branching ratios and g-factors are in good agreement with experimental values
