Abstract High-spin level structure of doubly odd nucleus 140Pr has been investigated via the 130Te(14N,4n)140Pr reaction at beam energies from 55 to 65MeV. Measurements of γ-ray excitation functions, γ-ray singles and γ-γ-t coincidences were performed with twelve BGO(AC)HPGe detectors. The level scheme of 140Pr, including 27 new levels and 42 new γ rays, has been established for the first time. The level structure is compared with those in the neighbouring odd--odd nuclei, and interpreted qualitatively.
