Direct measurement of transition frequencies in isolated $\overline{p}He^{+}$ atoms, and new CPT-violation limits on the antiproton charge and mass
A radio frequency quadrupole decelerator and achromatic momentum analyzer were used to decelerate antiprotons and produce p/sup 4/He /sup +/ and p/sup 3/He/sup +/ atoms in ultra-low- density targets, where collision-induced shifts of the atomic transition frequencies were negligible. The frequencies...
