| Abstract: | The mass of57Cu has been measured with the58Ni(14N,15C)-reaction at 150 MeV incident energy with theQ 3D-spectrometer. The reaction has been selected after a careful inspection of the DWBA-expression for the cross section with respect to the highest weighting factors for spins andl-transfer. Cross sections of several μb/sr have been obtained. TheQ-value has been measured to beQ 0=?19.90 (4) MeV and the57Cu mass excess is ?47 340 (40) keV. Four lines of excited states have been observed up to 5.7 MeV. These states have a structure of single particle character, since57Cu consists of a doubly closed core with N=Z=28 and a proton outside, and states up to the 2d 5-shell are observed. |
