Excited states in 142pm are investigated via the 128 Te(19F, 5n)142pm reaction at beam energies from 75 to 95 MeV by using techniques of in-beam γ-ray spectroscopy. Measurements of γ-ray excitation function, X-γ and γ-γ-tcoincidences are performed with 10 BGO(AC)HPGe detectors. Decay of the previously known 67-μs isomer in 142Pm is observed and added into the new level scheme. This isomer is definitely placed at the excitation energy of 2828.5 keV. The spin of this isomer is suggested to be 13h according to the measured γ-ray anisotropies.
