title = "(p, t) Reactions on odd-a nuclei and the weak-coupling core-excitation model",
abstract = "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.",

note = "Funding Information: Weak-coupling ideas are often invoked in nuclear structure to relate states of neighboring nuclei \[1\ ]. Ground states of odd-A nuclei are generally considered as an odd nucleon weakly coupled to the 0 + ground states (g.s.) of the even-even cores. The correctness of this picture is borne out by the large single-particle transfer (spectroscopic factor, S ~ 1) found in most such situations. The same picture is often invoked to relate collective 2 + and 3-states in heavy even-even nuclei with corresponding multiplets, obtained by weak coupling of a single particle, in adjoining odd-A nuclei. The essential requirement for the emergence of such a picture is that the coherence of the core state must be strong enough to be not destroyed by the coupling of the odd particle. The 0 + ground states (0{"}~) of even-even nuclei posses this property. The highly correlated nature of the lowest excited 0 + states (0~) which occur at modest excitation in most even-even nuclei, generally goes unrecognized unless they can be interpreted as the band heads of a rota- • 1 Now at Yale University, New Haven, Connecticut. • 2 On leave of absence from Institut fiir Kernphysik der J.W.
