Abstract
Several new features have been observed in the infrared spectrum of solid hydrogen when it was ionized by the bombardment of 3 MeV electrons from a van der Graaff accelerator at Argonne National Laboratory. The spectrum from 1800 to $7000 cm^{-1}$ of a 2 cm long crystal of hydrogen was recorded using a Bomem FTIR spectrometer at $4 cm^{-1}$ resolution. The observed lines have a very long lifetime similar to the features reported earlier in deuterium species subject to tritium $\beta ionization^{1}$ and high energy proton $bombardment.^{2}$ The interpretation of these features will be discussed based on the ab initio $calculations^{3}$ and earlier $experiments^{4}$ on ionic hydrogen clusters.
