The proton-rich isotope Cu-56 was produced at the GSI On-Line Mass Separato
r by means of the Si-28(S-32, p3n) fusion-evaporation reaction. Its beta -d
ecay properties were studied by detecting beta -delayed gamma rays and prot
ons. A half-Life of 93 +/- 3 ms was determined for Cu-56. Compared to the p
revious work, six new gamma rays and three new levels were assigned to the
daughter nucleus Ni-56. The measured Gamow-Teller strength values for five
Ni-56 levels are compared to shell-model predictions. (C) 2001 Elsevier Sci
