“…Many of the properties of the 1ow-lying states are described in terms of the pure ( f7/ p )" configuration. The description of the low-energy DCX experiments [7] performed on Ca, Ca, and Ca was therefore less complicated as far as nuclear structure goes, and Eq. (1) was applied successfully to the above nuclei [1,3].…”

Nuclear structure aspects of the double-charge-exchange (DCX) reaction on nuclei are studied. Using a variety of DCX-type two-body transition operators, we explore the influence of two-body correlations among valence nucleons on the DCX transition amplitudes to the isobaric analog state and to other nonanalog J =0+ states. In particular, the question of the spin dependence and of the range of the DCX transition operators is explored and the behavior of the transition amplitudes as a function of the valence nucleon number is studied. It is shown that the two-amplitude DCX formula derived by Auerbach, Gibbs, and Piasetzky for a single j configuration holds also in some cases when configuration mixing is strong. DCX-type transitions from the Ca and Ni isotopes to the Ti and Zn isotopes and from '6Fe to Ni are the subject of this study.PACS number(s): 25.80.Gn DCX transition operator which possesses the "pairing" property [4], i.e. , an operator that for even n satisfies

“…In the 1980s, the DCX reactions using pion beams that were produced in the three meson factories at LAMPF, TRIUMF, and SIN were performed. Studies at lower pion energies (E ≤ 50 MeV) have indeed produced clear signals of nucleon-nucleon correlations [1][2][3][4][5] and were successfully explained by the theoretical studies [6,7]. The pion DCX experiments discovered the double isobaric analog states (DIAS) [8,9].…”

The double Gamow-Teller strength distributions in even-A Calcium isotopes were calculated using the nuclear shell model by applying the single Gamow-Teller operator two times sequentially on the ground state of the parent nucleus. The number of intermediate states actually contributing to the results was determined. The sum rules for the double Gamow-Teller operator in the full calculation were approximately fulfilled. In the case that the symmetry is restored approximately by introducing degeneracies of the f -levels, and the p-levels in the f p-model space, the agreement with the sum rules was very close.
