Absolute cross sections for electron emission in the complete energy and angular ranges were measured for 30-MeV ${\mathrm{O}}^{n+}$+${\mathrm{O}}_{2}$ collisions at incident charge states of $n=4 \mathrm{to} 8$. Rises in inner- and outer-shell ionization of the target are studied for increasing $n$. Electrons ejected from the outer shell of the projectile are found to be very intense at forward emission angles $\ensuremath{\theta}$. Auger electrons from the projectile are observed at $\ensuremath{\theta}l42\ifmmode^\circ\else\textdegree\fi{}$ for $n$ as large as 6.

$\mathrm{Ne} K$ x-ray and Auger-electron production cross sections have been measured in 50-MeV Cl + Ne collisions for incident charge states of 5+ to 15+. The ionization cross section and mean fluorescence yield were derived from the data. A factor 20 rise in the x-ray cross section over the charge-state range studied is primarily due to a factor 7.2 increase in the mean fluorescence yield. The factor 2.8 rise in the ionization cross section can be explained by a decreased screening of the projectile nuclear charge.

The presence of isospin coupling in the incident channel is observed as anomalous behavior in $^{98}\mathrm{Mo}$+$p$ excitation functions for proton, deuteron, and triton outgoing channels. Similarly shaped anomalies are simultaneously observed in several channels at threshold energies for the ($p, n$) reaction to the ground-state analog and to excited-state analogs of $^{98}\mathrm{Mo}$. The latter imply coupling through a deformation of the isospin-dependent potential.

Angular distributions to 18 states in 208Pb populated by 208Pb(p,p′)208Pb were measured at an incident energy corresponding to the g 9 2 resonance in 209Bi. Total inelastic widths are extracted and some tentative spin assignments are made.

Intense discrete optical transitions have been observed in Ne, Ar and Kr excited by 30 MeV oxygen ions. Coincidence measurements show that the transitions are not correlated with inner-shell Auger transitions.

Proton inelastic scattering excitation functions to various final states in 208Pb which resonate strongly at one analog resonance have been fitted by a five parameters formula. For each of the seven observed single-particle analog resonance in 209Bi consistent values for the total width, Γ, and resonance energy, E0, were found.
