• Excited 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.
