Summary
We have compared a simple nonrelativistic wave-function model of the deuteron to what we believe to be its completely relativistic counterpart, followingCutkosky (1) andJones (2). The result is an ansatz hich allows one to make a plausible modification of more sophisticated wave-function models to a manifestly covariant form. This ansatz is used in reanalyzing low momentum transfer elastic e-d scattering to yield the neutron charge-form factor. Our conclusion is that the surprisingly rapid curvature of this form factor at low momentum transfer as previously noted (2) remains and is even somewhat increased if the ansatz is used.
Riassunto
Si è confrontato un semplice modello di funzione d’onda non relativistico del deutone con quello che crediamo essere il suo equivalents completamente relativistico, seguendo Cutkosky e Jones. II risultato è una posizione che permette di modiflcare in modo accettabile modelli di funzione d’onda più raffinati in forma manifestamente covariante. Si usa questa posizione per rianalizzare lo scattering elastico e-d di piccolo momento trasferito allo scopo di ottenere il fattore di forma della carica del neutrone. Si conclude che la curvatura sorprendentemente rapida di questo fattore di torma a piccolo momento trasferito resta ed anzi cresce un poco, come è stato già notato, se si usa questa posizione.
