Mirror Energy Differences and nuclear structure in 1f[sub 7∕2] nuclei

Experimental mirror energy differences along yrast bands of nuclei lying in the middle and the second part of 1f7/2 shell are compared with shell model calculations in the 1f7/2 and in the full pf configuration spaces, as well as with CSM calculations. MED plots are consistent with the description which emerges from the interpretation of SM calculations: i.e. the band crossing of the gs band with high‐K bands in A = 51 mirror pairs, as well as the seniority‐3 quasi band‐termination at Iπ = 19/2− in A = 49. Rotational alignment effects are excluded, contrarily to what even recently proposed. Some inconsistencies are pointed out in the topical literature.
