High-spin level scheme of odd-odd 140Pr nucleus

High-spin level structure of doubly odd nucleus 140Pr has been investigated using in-beam γ spectroscopy techniques by means of the 130Te(14N, 4n)140Pr reaction at beam energy of 58 MeV. γ-ray excitation functions, γ-ray singles and γ-γ-t coincidences were measured experimentally. The level scheme of 140Pr, including 27 new levels and 42 new γ-rays, was established for the first time up to 4717.3 keV in excitation energy. Based on the measured γ-ray anisotropies, spin values were suggested to the levels in 140Pr. Several quasiparticle configurations are discussed on the basis of systematics in the neighboring odd-odd nuclei, and interpreted qualitatively
