Description

The T=1 admixture into the T=0 member of a recently discovered Jπ=4+ isospin-doublet in 54Co is obtained from the measured electromagnetic E2/M1 multipole mixing ratio, δ=0.12(4) of the T=0,4+→T=0,3+ transition. Combining these data with shell model calculations for strong isovector M1 and isoscalar E2 electromagnetic matrix elements one obtains a value for the T=1 admixture into the T=0,4+ state of 0.23-0.10+0.29%. The corresponding mixing matrix element in the 4+ doublet is Vmix=10 keV. (orig.)
