EXPERIMENTAL-THEORETICAL LANDAU ENERGY-LEVEL DATA AND ITS USE IN MAKING P-GE LASER TRANSITION ASSIGNMENTS

Landau energy levels are determined from cyclotron resonance absorptio n data and compared to theoretical calculations. Energy level diagrams are presented to graphically display the nonequal energy level spacin gs and identify absorption transitions. This information is then used to make transition assignments responsible for the p-Ge laser signals seen by V. N. Shastin et al. and C. Kremser et al. This work suggests that the p-Ge laser yields signals via the following transitions: (a) the expected cyclotron transitions for Delta n = 1, (b) harmonic cyclo tron transitions for Delta n = 2, 3, (c) light-to-heavy hole transitio ns and (d) light hole to acceptor level transitions. The material of t his paper should be of aid in the study of the pumping-oscillation cyc le of the p-Ge laser.
