Small-angle scattering and absorption of 3.0 GeV/c antiprotons in nuclear emulsion

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

The eikonal approximation of the optical model is used to analyse the elastic and inelastic interactions of 3.0 GeV/c antiprotons in nuclear emulsion. The aim was to find the value of the real part of the nuclear scattering amplitude. The best fit with the experimental data was obtained with the following parameter values:R 0=1.57 fermi,W=22.4 MeV,V 0=2 MeV, yielding a ratio of the real to imaginary part of the scattering amplitude of 5%.

Riassunto

Si è usata l'approssimazione iconale del modello ottico per studiare le interazioni elastiche ed anelastiche di antiprotoni di 3.0 GeV/c nell'emulsione nucleare allo scopo di trovare il valore della parte reale dell'ampiezza di scattering nucleare. La migliore approssimazione ai dati sperimentali è stata ottenuta con i seguenti valori dei parametri:R 0=1.57 fermi,W=22.4 MeV,V 0=2 MeV, ottenendo un rapporto del 5% fra la parte reale e la parte immaginaria dell'ampiezza di scattering.
