Summary
In the multiple-scattering theory of K−-deuterium interactions, the first-order correction to the zeroth-order (asymptotic) value of the K−-deuterium elastic scattering amplitude is calculated, using Kohn’s variational method for nuclear collisions. A comparison between the variational and the transition probability methods for the calculation of K−-d elastic scattering amplitude shows that as a function of K− momentum, the variational method gives slightly smaller values of the scattering amplitude.
Riassunto
Si calcola, nella teoria dello scattering multiplo delle interazioni K−-deuterio, la correzione di primo ordine al valore di ordine zero (asintotico) dell’ampiezza dello scattering elastico K−-deuterio, facendo uso del metodo delle variazioni di Kohn per le collisioni nucleari. Un confronto fra il metodo delle variazioni e quello della probabilità di transizione per il calcolo dell’ampiezza dello scattering elastico K−-d mostra che, in funzione dell’impulso dei K−, il metodo delle variazioni dà valori dell’ampiezza di scattering leggermente minori.
