Hyperfine transitions in ground state hydrogen-like {sup 165}Ho{sup 66+} and {sup 185,187}Re{sup 74+}
- Lawrence Livermore National Laboratory, Livermore, California 94550 (United States)
Spontaneous line emission due to the hyperfine splitting of the ground state of highly charged hydrogen-like ions excited by electron collisions was measured using an Electron Beam Ion Trap. The F=4 to F=3 transition of the 1s {sup 2}S{sub 1/2} configuration of {sup 165}Ho{sup 66+} was identified at (5726.4{plus_minus}1.5){Angstrom}. The F=3 to F=2 transition for the two isotopes {sup 185,187}Re{sup 74+} were found at (4512{plus_minus}2){Angstrom} and (4557{plus_minus}2){Angstrom}. We infer the nuclear dipole magnetic moment of {sup 165}Ho to be 4.1267(11) n.m., with five times higher accuracy than previous measurements. For {sup 185,187}Re we determine 3.153(2) n.m. and 3.184(2) n.m., respectively, in disagreement with a tabulated NMR measurement. {copyright} {ital 1997 American Institute of Physics.}
