Summary
Momentum space Faddeev equations that include also the Coulomb force are solved for the3H and3He binding energies. Separable nucleon-nucleon potentials with varying deuteronD-state probability are for the first time employed in a momentum space3He binding energy calculation utilizing an angular-momentum truncation. The resulting Coulomb energy roughly scales with the trinucleon binding energy. Coulomb energies calculated with a separable representation of the Paris potential are compared with configuration space results obtained with local potentials.
Riassunto
Si risolvono le equazioni di Faddeev dello spazio dei momenti che includono anche la forza di Coulomb per le energie di legame3H e3He. I potenziali separabili nucleone-nucleone con probabilità variabile dello statoD del deuterone sono utilizzati per la prima volta per un calcolo dell'energia di legame dell'3He nello spazio dei momenti utilizzando un troncamento del momento angolare. L'energia risultante di Coulomb varia di scala approssimativamente con l'energia di legame del trinucleone. Le energie di Coulomb calcolate con una rappresentazione separabile del potenziale di Paris sono confrontate con i risultati dello spazio delle configurazioni ottenuti con potenziali locali.
