Measurement of the temperature dependence of dwell time and spin relaxation probability of Rb atoms on paraffin surfaces using a beam-scattering method

The scattering of Rb atoms on an anti-relaxation coating was studied. No significant change in the spin relaxation probability by single from a tetracontane surface observed cooling film 305 to 123 K. mean dwell time estimated using time-resolved method.Delay-time spectra, which times can be estimated, were measured at 305, 153, and K, with window $9.3\times 10^{-5}$ s. increase K smaller than $4.4\times 10^{-6}$ s, is significantly value expected room temperature Larmor frequency shift. These results explained assuming small number components, least three orders magnitude longer majority component.
