Coalescence of Light Particles in the ReactionO16+U238at 315 MeV

Abstract

The energy spectra of light particles ($p$,$d$,$t$) produced in $^{16}\mathrm{O}$-induced reactions on $^{238}\mathrm{U}$ at 315 MeV can be rather well described by thermal distributions in a rest frame that moves with about half the beam velocity. The energy spectra of deuterons and tritons can be related to the proton energy spectra by a coalescence model that incorporates Coulomb effects.
