Abstract

Single and double [Formula Presented]-shell excitation of Li by 10.6-MeV/nucleon [Formula Presented] projectiles is investigated by measuring Li autoionization spectra in the energy range from 50 to 90 eV. The ratio for double [Formula Presented]-shell excitation to single [Formula Presented]-shell excitation is determined to be about 0.36%. The measured ratio for double-to-single [Formula Presented]-shell excitation of Li is about a factor of 2 larger than calculations based on independent interactions between the projectile nucleus and each of the Li target electrons, indicating that the electron-electron interaction plays a dominant role in the double [Formula Presented]-shell excitation of Li in these collisions.
