Excited 7 2- states to which enhanced L = 0 (p, t) transitions are observed have been identified in 41Ca at 2958 keV and in 57Co at 2611 keV. A comparison of these (p, t) transitions with those to the 0+ states in 40Ca at 3353 keV and in 58Ni at 2940 keV leads to the conclusion that these states are obtained by weak-coupling of a f 7 2 particle and hole, respectively, to the excited 0+ states of the doubly even cores. It is suggested that these cases are examples of a rather general weak-coupling phenomenon.
