We report measurements of d¯, p¯, K⁻, and π⁻ produced at 0° in collisions of 14.6{ital A} GeV/c²⁸ Si on Al, Cu, and Au targets. A beam-line focusing spectrometer was used to identify particles at rigidities from -2 to -8 GV. The ratio of d

We report measurements on the angular distributions of, and correlation between, projectile and target fragments emitted in high-multiplicity, peripheral collisions of 0.85A GeV /sup 238/U nuclei with Ag(Br) nuclei. The observations are amenable to a

Heavy-ion beams at the Lawrence Berkeley Laboratory Bevatron are routinely available for calibration purposes. These beams are very useful to cosmic-ray physicists and others who wish to have empirical evidence indicating their instruments really can

We have performed an experimental study of the angular and momentum distributions of fragments emitted from central collisions between emulsion nuclei (AgBr) and heavy-ion projectiles /sup 4/He, /sup 1/6O, and /sup 4/0Ar at beam rigidity 5.72 GV. Cen

Yields of neutron-rich projectile fragments have been measured at 0\ifmmode^\circ\else\textdegree\fi{} for the reaction of 212-MeV/amu $^{48}\mathrm{Ca}$ ions on an 890-mg-${\mathrm{cm}}^{\ensuremath{-}2}$ beryllium target. Fourteen nuclides have bee

The fragment momentum distributions in the projectile rest frame are, typically, Gaussian shaped, narrow, consistent with isotropy, depend on fragment and projectile, and have no significant correlation with target mass or beam energy. The nuclear te

Two independent emulsion experiments using Bevalac beams of {sup 16}O and {sup 56}Fe at {approx}2 GeV/nucleon find with > 99.7% confidence that the reaction mean-free paths of projectile fragments, 3 {approx}< Z {approx}< 26, are shorter for a few ce
