“…As dipole mixing is added into the transition, the anisotropy changes sign twice, the first time at a mixing ratio of about 0.2. The lack of evidence for an anisotropy in our data as well as in Kitano et al [7] for the 408 keV line implies that there may be some small amount of dipole mixing in the transition. More data are required to determine the nature of the transition more conclusively.…”

“…They have never been applied to EDM measurements of small amounts of short-lived radon isotopes. Although the polarizations of 209 Rn and 223 Rn have been demonstrated [7], measurements were done at only one cell temperature, precluding the study of the radon polarization and relaxation parameters. In preparation for EDM measurements using the octupole-enhanced 223 Rn, the polarization of 209 Rn by spin exchange with laser-polarized alkali metals is studied.…”

“…With |d( 199 Hg)| < 2.10 × 10 −28 e · cm [12], a measurement of the 223 Rn EDM with a sensitivity of 10 −26 e · cm or better would be a significant improvement. This appears feasible at current and future rare isotope production facilities using NMR with laser-polarized noble gases [13] combined with γ -ray anisotropy [14] or β asymmetry [15] detection techniques. Earlier work at ISOLDE [14] demonstrated polarization of 209 Rn and 223 Rn by spin exchange with laser optically pumped potassium and measured the magnetic moment of 209 Rn; however, the polarization and relaxation mechanisms were not studied in detail and cell coatings were not explored.…”

This article reports new techniques applied at the Stony Brook Francium Lab [16] to measure, for the first time, the temperature dependence of radon polarization in coated and uncoated glass cells at several temperatures.…”

“…aligned the nuclear spin of some radioactive noble gases using the technique of SEOP and studied their magnetic moment by measuring the gamma emission asymmetry [12]. Soon after that more experiments were conducted using the same technique [49,106]. These experiments located NMR lines of various radioactive nuclei by monitoring the change of photon count rates while disturbing the nuclear polarization by broadcasting an RF frequency.…”
