Is effectively free of quadrupole (or gradient) Stark shifts which may plague competing ion frequency Of the nuclear magnetic dipole, electric quadrupole, and perhaps magnetic octopole moments.įinally, the hyperfine structure of 137 Ba+ yields an optical transition with unique advantages in a Spectroscopy scheme could measure this structure to parts in 10−8 or better, allowing a determination The metastable 5D3/2 state is currently known to a precision 10−4. Violation experimental concept and describe new ideas.ĭuring the study of the nuclear spinless (I = 0) isotope of Ba+, we discovered several worthwhileĮxperimental goals for an isotope with nuclear spin,īa+ (I = 3/2). Which knowledge of dipole matrix elements is an important prerequisite. Such experimental tests in Ba+Īre in high demand since knowledge of key dipole matrix elements is currently limited to about 5%.īa+ has recently been the subject of theoretical interest towards a test of atomic parity violation for These resultsĬonstitute a new high precision test of heavy-atom atomic theory. (or ac-Stark effect) in these states to a precision of 10−3 at two different wavelengths. We employ this technique to measure the ratio of off-resonant light shifts Ion electron spin resonance experiments in both the ground 6S1/2 and metastable 5D3/2 states at Several projects developed to study the structure of singly-ionized barium and more fundamentalįirst, we describe a spin-dependent ‘electron-shelving’ scheme that allows us to perform single Single trapped ions are ideal systems in which to test atomic physics at high precision: they are effectively isolated atoms held at rest and largely free from perturbing interactions.
