The dissociative electron attachment (DEA) process in electron-H{sub 2} molecule collisions, involving the {sup 2}{sigma}{sub g}{sup +} excited electronic Rydberg state of molecular hydrogen ion H{sub 2}{sup -}, 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.
