Abstract
The method of level-crossing spectroscopy has been employed to measure the hyperfine interaction constants and the lifetimes of the and states of . The parameters for the states were obtained from a conventional level-crossing experiment; it was also possible to measure the magnetic dipole hyperfine structure constant for states by using a newer method (similar to level crossing) called the "decoupling" method. With these techniques, it was possible to measure for the , , and states of . These measurements, together with the measurement of for the state, made it possible to infer the nuclear quadrupole moment of . In order to check the consistency of the values obtained from the decoupling runs, data were taken (using the decoupling method) for for the and states of . In addition to the hyperfine data, the lifetimes for the and states were also obtained. The results are: MHz, MHz, MHz, MHz, MHz, MHz, nsec, nsec, and mb.
