| Abstract: | The nuclear wave functions of the A = 13 ground state isodoublet system are analysed by constraining them (within the 1p shell) to fit the best available electromagnetic and weak data. It is found that the wave functions are dominated by only two basis states of the possible five, with a greater degree of configuration mixing than that predicted by Cohen-Kurath. The use of these phenomenological wave functions to study 13C(γ, π−)13Ng.s. at low energies gives better agreement with data than using Cohen-Kurath wave functions but a factor of three enhancement still persists. |
