Highly resolved Doppler shifted peaks of the hydrogen Balmer lines, resulting from charge exchange of H+, H2+, and H3+ with an H2 gas target, were obtained without the need for a deconvolution procedure. This enabled the unambiguous determination of the chemistry of these hydrogen species in the units of mTorr pressure range. This was obtained from a gaseous discharge using a biconical hollow cathode that yielded a well collimated and monoenergetic beam.
