Measurement of spin-exchange and relaxation parameters for polarizing {sup 21}Ne with K and Rb
- Department of Physics, Princeton University, Princeton, New Jersey 08544 (United States)
Hyperpolarized K-{sup 3}He comagnetometers have been used for tests of fundamental physics and inertial rotation sensing. These experiments will demonstrate increased sensitivity if the {sup 3}He buffer gas is replaced with {sup 21}Ne. We measure the parameters necessary to realize implementation of an alkali-metal-{sup 21}Ne comagnetometer for two promising alkali-metal species, Rb and K. The spin-exchange rate constant for K with {sup 21}Ne and Rb with {sup 21}Ne are measured using two different methods. We also make the first measurement of the K-{sup 21}Ne contact spin interaction. Measurements for the Rb-{sup 21}Ne contact spin interaction, as well as the spin-destruction coefficients for {sup 21}Ne with both alkali-metal species are consistent with previous measurements. Additionally the quadrupolar spin-relaxation rate of {sup 21}Ne is measured. Finally, the feasibility of utilizing polarized {sup 21}Ne for operation in a comagnetometer is discussed.
