分析了最近发现的54 Co中同位旋量子数T = 0和T = 1的4（+）态的二重态的同位旋混合。结果表明，测量的E2/M1多极混合比可以用来估计这些态的同位旋混合。结合新的实验数据和壳模型计算的结果，发现同位旋混合的量约为0.2%。
Isospin mixing of the recently discovered doublet of 4(+) states with isospin quantum numbers T = 0 and T = 1 in 54Co 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 approximately 0.2%.
