Low-lying levels in {sup 57}Cu and the {ital rp} process
- Cyclotron Institute, Texas A&M University, College Station, Texas 77843 (United States)
The level scheme of {sup 57}Cu is investigated via the {sup 1}H({sup 58}Ni,{sup 57}Cu-{gamma})2{ital n} reaction by using the recoil mass spectrometer MARS at the Texas A&M Cyclotron Institute. Three low-lying excited states are observed in {sup 57}Cu at 1028 {plus_minus} 4, 1106 {plus_minus} 4, and 2398 {plus_minus} 10 keV. The results are compared with well known excited states of the mirror nucleus {sup 57}Ni. The measured excited states of {sup 57}Cu allow recalculation of the astrophysical reaction rate for the stellar radiative proton capture reaction {sup 56}Ni({ital p},{gamma}){sup 57}Cu. {copyright} {ital 1996 The American Physical Society.}
