摘要：

Isospin mixing of the recently discovered doublet of 4(+) states with isospin quantum numbers T=0 and T=1 in Co-54 is analyzed. It is shown that the measured E2/M1 multipole mixing ratios can be used to estimate the isospin mixing of these states. Combining the new experimental data with results of a shell model calculation, the amount of isospin mixing is found to be approximate to0.2% .
