RESEARCH INVESTIGATION DIRECTED TOWARD EXTENDING THE USEFUL RANGE OF THE ELECTROMAGNETIC SPECTRUM.
Abstract
Continuous oscillation was achieved with an optically pumped Rb87 maser. This device oscillates at 6835 Mc/sec, corresponding to the hyperfine splitting of the ground state of Rb87. The hyperfine coupling constants due to quadrupole, spin-rotation, and spin-spin interaction were determined for NH2D. A detailed electron nuclear double-resonance (ENDOR) study of the self-trapped hole in LiF was completed. An experiment was initiated to examine superconducting tunneling in the presence of energy-gap radiation. Preparations were completed for applying the optical maser homodyne spectrometer to a study of critical opalescence, and preliminary spectra were observed. Initial attempts to observe photon echos indicated the need for more data on relaxation processes in ruby at low temperature.
