On DCX Nuclear Matrix Elements: Shell Model and QRPA results

CIVITARESE, O.; TARUTINA, TATIANA

Conferencia; MEDEX'23; 2023

In this talk we are presenting and discussing our results for someDouble Charge Exchange (DCX) systems. The calculations are performed for light and heavy nuclei participant in the reactions. The microscopic structure ( wave functions and energy spectra) of the light nuclei is given in terms of shell model results. For the heavy mass partners we use the Quasiparticle Random Phase Approximation (QRPA). Attention is paid to the explicit equations which described the transfer of neutrons and protons between projectile and target nuclei, as well as to the dependence of the currents upon the momentum transferred between nuclei. The present results are compared with other results available in the literature and the differences between them are discussed. The possible relationship between DBD and DCX nuclear matrix elements is analysed as a function of the momentum.
