ResumoExcited levels of 62 Zn were studied by means of the (p, t) reaction at 51.9 MeV and of the in-beam gamma-ray spectroscopy using the 63 Cu(p, 2nγ) 62 Zn reaction. The triton angular distributions in 64 Zn(p, t) 62 Zn and the gamma-ray spectra in 63 Cu(p, 2nγ) 62 Zn were obtained. Twenty excited levels up to 5.56 MeV of 62 Zn were observed at the excitation energies of 0.954, 1.805, 2.186, 2.38, 2.75, 2.80, 3.22, 3.44, 3.78, 3.93, 4.00, 4.16, 4.32, 4.60, 4.75, 4.86, 5.02, 5.09, 5.40 and 5.56 MeV. The excited states at 0.954, 1.805, 2.186 2.38, 3.22, 3.44. 3.93, 4.32 and 5.02 MeV were concluded to have J π of 2 + , 2 + . 4 + , 0 + , 3 - , 2 + , 0 + , 3 - and 4 + , respectively. The branching ratio in the decay of the second 2 + state was determined as I(2 2 + →2 1 + )/I(2 2 + →0 g.s. + )=60/40. The nuclear properties of the low-lying states of 62 Zn are discussed in detail in comparison with other nuclei in this regeon.
