Collective structures in 62Cu

The spectroscopy of 62Cu is studied via the 54Cr(12C, 1 p3n) 62Cu fusion-evaporation reaction. On the basis of the gamma -gamma coincidence analysis, angular distributions from oriented states, and linear polarization measurement, three positive-parity and three negative-parity level sequences in 62Cu are observed, including two new gamma -ray transitions and one new level. The collective structures are discussed in terms of the tilted axis cranking covariant density functional theory. Although not firmly confirmed in experiment, the properties of a magnetic rotational structure with the n(f7/2)-1(p3/2 f5/2)2 circle times v(g9/2)1(p3/2 f5/2)4 configuration have been discussed. Its angular momentum generation is probably due to the shears mechanism.
