Cross sections for vibrational excitation of H2 via electronically excited singlet states populated by low energy electron impact

Absolute cross sections are calculated for excitation of hydrogen, H2(X 1Σsub(g)sup(+), upsilon'' = O) on its different vibrational levels, by radiative decay from the B, B', C, and D electronic singlet states first populated by low energy electron collisions. The cross sections present a maximum around 50 electron-volts, but about 20 to 40% higher than those reported by Hiskes considering the same excitation process only through the B and C electronic singlet states
