Target-A Dependence Of Light-Ion Emission From Reactions Induced By 100-Mev/U O-16

The target-$A$ dependence of cross sections for emission of energetic $Z=1$, 2 particles from 100-MeV/u $^{16}\mathrm{O}$ on Al, Ni, Sn, and Au targets is found to vary from an ${A}^{\frac{1}{3}}$ dependence at small angles to $\ensuremath{\approx}{A}^{\frac{2}{3}}$ at $\ensuremath{\theta}g45\ifmmode^\circ\else\textdegree\fi{}$, suggesting a smooth transition from peripheral to central collisions. The $A$ dependence of $^{2}\mathrm{H}$ and $^{3}\mathrm{H}$ yields indicate that target neutrons contribute to the formation of these particles. Velocity and temperature parameters of a heated, moving source are given for projectile energies from 7.5 to 147 MeV/u.
