Low-lying levels in Cu-57 and the rp process
MetadataShow full item record
The level scheme of Cu-57 is investigated via the H-1(Ni-58,Cu-57-gamma)2n reaction by using the recoil mass spectrometer MARS at the Texas AandM Cyclotron Institute. Three low-lying excited states are observed in Cu-57 at 1028 +/- 4, 1106 +/- 4, and 2398 +/- 10 keV. The results are compared with well known excited states of the mirror nucleus Ni-57. Th, measured excited states of Cu-57 allow recalculation of the astrophysical reaction rate for the stellar radiative proton capture reaction Ni-56(p,gamma)Cu-57.
