Abstract :
Ground-state hyperfine splitting of /sup 113/Cd/sup +/ ions has been measured using an RF trap technique. The transition was detected with a laser microwave double-resonance method in the presence of He buffer gas. We determined the splitting to be 15 199 862 858 Hz. The preciseness of the value was improved over that in previous data by seven orders of magnitude.
