Suppression of soft nuclear bremsstrahlung in proton-nucleus collisions
M. J. van Goethem, L. Aphecetche, J. C. S. Bacelar +19
Photon energy spectra up to the kinematic limit have been measured in 190 MeV proton reactions with light and heavy nuclei to investigate the influence of the multiple-scattering p…

Hard photon and neutral pion production in cold nuclear matter
L. Aphecetche, J. Bacelar, H. Delagrange +19
The production of hard photons and neutral pions in 190 MeV proton induced reactions on C, Ca, Ni, and W targets has been for the first time concurrently studied. Angular distribut…

Thermal bremsstrahlung probing the thermodynamical state of multifragmenting systems
D. G. d'Enterria, L. Aphecetche, A. Chbihi +20
Inclusive and exclusive hard-photon (E 30 MeV) production in five different heavy-ion reactions (Ar+Au, Ag, Ni, C at 60{\it A} MeV and $^{…
