Title: Subnanosecond lifetime measurement for the T=0,3{sub 1}{sup +} state of odd-odd N Z {sup 58}Cu

Abstract

We have measured the lifetime of the T=0,J{sup {pi}}=3{sub 1}{sup +} state of {sup 58}Cu at 444 keV. The excited states in {sup 58}Cu were populated with the {sup 58}Ni(p,n{gamma}) reaction at the SUNY at Stony Brook TANDEM-LINAC facility. A lifetime {tau} = 0.468 {+-} 0.085 ns was found with the delayed {gamma}-radiofrequency coincidence method with respect to the pulsed LINAC beam. It corresponds to an isoscalar E2 transition strength of 7.6 {+-} 1.4 W.u. to the T=0,J{sup {pi}}=1{sub 1}{sup +} ground state. The result agrees with the interpretation of the 3{sub 1}{sup +} state as a collective quadrupole excitation of the 1{sub 1}{sup +} ground state of {sup 58}Cu.
