A series of spectral measurements were carried out to demonstrate the feasibility of achieving stimulated emission in the vacuum ultraviolet using molecular xenon gas excited by a relativistic electron beam from a Febetron 705. Both longitudinal and transverse excitation schemes were used with gas pressures up to 30 atmospheres. The xenon emission spectrum at 3 atm consisted of a 150A wide band centered around 1750A. At higher pressures 20 atm indication of a preferential intensity build up at several parts of the spectrum was recognizable over the broad continuum. This preferential build up disappeared when one of the cavity mirrors was taken out. Since no significant line narrowing was observed, the conclusion from the spectral studies using the Febetron 705 is that the evidence of stimulated emission in molecular xenon is at best marginal.
