Abstract
The Paschen alpha line (1875.1 nm) of the excited hydrogen atom (4s,4p ,4d,4f) produced in e-H-2 collisions was observed with a grating spect rometer equipped with a PbS detector. The emission cross sections were determined for the electron energy of 100-1000 eV, and were about hal f as much as those of the Balmer beta line of the excited hydrogen ato m (4s,4p,4d). The Fano plot indicated that the Paschen line was excite d mainly through optically allowed processes as in the case of the Bal mer lines.
