Pagination or Media Count:
A number of projects involving the optical detection of energy level crossings are described, including work on various isotopic species of Zn and Cd. Results are given for the lifetimes of certain of these states. A new experiment is described for the measurement of the hyperfine structure of Li ions. Several optical double resonance studies are reported, including work on Na and radioactive Cd. New experimental programs are described in microwave spectroscopy of molecules, the production of cryogenic magnets, and a rubidium atomic clock. Final results are given for measurements of the O17H free radical. Microwave and optical maser research is discussed. A new experiment for measuring the microwave properties of simulated planetary atmospheres is in progress.
