Antiproton-deuteron low-energy cross-sections

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

Summary

About 45000 interactions of antiprotons of kinetic energy between 57 and 170 MeV have been measured in a deuterium bubble chamber. Total and annihilation cross-sections have been determined at 9 values of the antiproton energy together with the differential crosssection dσ/dt for scattering events. In spite of the peculiar behaviour of the deuteron target at these low energies a reliable measure of the antiproton-neutron annihilation cross-section has been obtained.

Riassunto

In camera a bolle a deuterio sono state misurate circa 45000 interazioni di antiprotoni di energia cinetica compresa fra 57 e 170 MeV. Le sezioni d'urto totali e di annichilazione sono state determinate a 9 valori dell'energia dell'antiprotone incidente; agli stessi valori sono state misurate anche le sezioni d'urto differenziali dσ/dt per gli eventi di diffusione. Nonostante il particolare comportamento del deuterone bersaglio a queste basse energie, si ottiene un'attendibile misura della sezione d'urto di annichilazione antiprotone-neutrone.
