Abstract

The dissociative electron attachment (DEA) process in electron-H[sub]2 molecule collisions, involving the ^2Σ^+[sub]g excited electronic Rydberg state of molecular hydrogen ion H[sub]2^−, is investigated theoretically. The DEA cross section has been calculated within the local complex potential approximation. The convoluted cross section, which presents a peak located at the incident energy of about 14 eV, compares favorably with available experimental data.
