Abstract : The report furnishes the observation and analysis of the pressure shift of 130 emission lines of metal atoms (in the region 2947-5900A) produced by various relative densities of argon and helium by means of a ballistic compressor. Eighty of these lines belonged to FeI; the remainder were due to CrI, CuI, MnI, NiI, NaI, CaI and CaII. The temperatures of compressed gases were 3230K (r.d. varied from 28-104) for argon, and 3600K (r.d. ranged from 36-108) for helium. Observations were also made on the shift of metal lines at various temperatures under a constant r.d. of argon. A comparison of the relative displacement of iron levels which differed in only one of the following: their j-value, L-value, multiplicity, or electron configuration suggested four general statements.
