The dominant role of the nuclear surface in (p, t) reactions

It is demonstrated in finite-range DWBA analyses of (p, t) reactions, utilizing realistic triton wave functions, that the transfer only occurs in the extreme surface of the nucleus. This explains in part the success of recent (p, t) analyses which employed quite simple two-neutron transfer form factors. The necessary enhancement of the bound-state wave functions was obtained by employing a «large geometry» in the half-separation energy method.


Si dimostra nelle analisi DWBA ad intervalli finiti delle reazioni (p, t), utilizzando funzioni d’onda reali del tritone, che il trasferimento si verifica solo nell’estrema superficie del nucleo. Questo spiega in parte il successo delle recenti analisi (p, t) che hanno fatto uso di fattori di forma abbastanza semplici per il trasferimento di due neutroni. È stato ottenuto l’accrescimento necessario delle funzioni d’onda di stato legato servendosi di una «geometria allargata» nel metodo dell’energia di semiseparazione.
