The atomic-beam magnetic-resonance flop-in technique was used to determine the hyperfine-structure separations and the hyperfine-structure anomaly between the isotopes Li/sup 6/ and Li/sup 7/; this technique was also used to measure the hyperfine-structure separations of the isotopes Re/sup 186/ and Re/ sup 188/. The separated-oscillatory-field method of Ramsey was used to very accurately determine the hyperfinestructure separations in Li/sup 6/ and Li/sup 7/ . The hyperfine-structure anomaly was determined using the separation values. The magnetic-dipole-interaction constant and the electricquadrupole-interaction constant were measured for the two radioactive isotopes of rhenium in the J = 5/2 ground state. Beams were produced by electron bombardment of irradiated rhenium wires. The spins of both isotopes were determined previously to be one. The nuclear moments of both isotopes were determined to be positive. An improved value for the electronic Lande g factor for rhenium was also obtained, with the result g = --1.95203(8). (auth)
