We present a method for measuring surface interaction parameters of spin-polarized Rb atoms on coated Pyrex glass surfaces based on edge enhancement in optically pumped Rb vapor. The best fit to the measured magnetic resonance lines using a theoretical model yields a dwell time τs =1.8 μs and a spin relaxation probability ξs =0.015 for a spin-polarized Rb atom on a Pyrex glass surface coated with dichlorooctamethyl-tetrasiloxane (Surfasil), and τs =0.5 μs and ξs =0.001 on a surface coated with octadecyltrichlorosilane (OTS).
