Abstract
Metastable, autoionizing high-spin states are studied using the ion-beam time-of-flight method in connection with single-collision excitation. High-resolution, time-delayed spectra are obtained from Li, Be, and B excited in 200-keV impact on C Evidence is found for the state in B ii. Excitation energies for the observed quartet and quintet states are given, and the branching ratio associated with the B ii decay is estimated.
