Abstract: (APS)
Double-charge-exchange reactions induced by pions furnish a direct means of detecting nucleon-nucleon correlations in nuclei. For the particular case of double isobaric analog transitions the effect of correlations is easily isolated and quite strong. We show that the magnitudes of the double-charge-exchange cross sections for the isotopes Ca42, Ca44, and Ca43, recently measured at low energies, can be explained well by our taking account of the position correlations of the valence neutrons in the respective ground states.- CORRELATION: (2NUCLEON)
