Abstract

The Schrödinger equation for a twonucleon problem with velocitydependent forces contains an integral operator the kernel of this might be approximated by a separable kernel then the equation can be easily solved A method to construct the best separable approximation is given the goodness of which is expressed in a simple way with the eigenvalues It turns out that a reasonable approximation is possible if the first eigenvalue of the kernel is nondegenerate and widely separated from the next one The properties of the approximation remain unchanged in momentum space representationL’equazione di Schrödinger per un problema di due nucleoni con forze dipendenti dalla velocità contiene un operatore integrale il nocciolo di questo si può approssimare con un nocciolo separabile in tal caso l’equazione può essere facilmente risolta Per costruire la migliore approssimazione separabile si mostra un metodo la bontà del quale è espressa in maniera semplice con gli autovalori Da ciò risulta che è possibile una approssimazione ragionevole se il primo autovalore del nocciolo è non degenere e largamente separato dal successivo Le proprietà dell’approssimazione restano immutate nella rappresentazione nello spazio degli impulsi
