Da. Church et al., COLLISIONS AND SPECTROSCOPY OF COLD, HIGHLY-CHARGED HIGH-Z IONS IN RETRAP, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 132(2), 1997, pp. 335-343
Recent experimental results from the RETRAP apparatus, including elect
ron capture measurements on highly charged high-Z ions and laser cooli
ng of a mixed cloud of Be+ and Be2+ ions, are briefly described. These
results are used as a basis for discussion of planned spectroscopy me
asurements on hydrogen-like and beryllium-like high-Z highly charged i
ons. Experimental parameters for potential measurements of the ground
state hyperfine structure of a hydrogen-like high-Z ion, and the g-fac
tor of the electron bound in that ion, are emphasized. (C) 1997 Elsevi
