    suggests a different numerical assignment for the nuclear matrix element with out the factor A1/3, for the two cases O16 and Ge72. His estimaie of (∑rp2) ≈ (1.5 - 2.0)(½ (e2/mc2))2 is too small by a facto three for the transition in RaC'. We do not feel that the data warrant a significant distinction between the two assignments.
