The first detailed study of surface spin relaxation of 199Hg atoms and identified dipolar coupling to paramagnetic sites as the likely source of spin relaxation was performed. Based on results of such studies, a reliable procedure for fabrication of Hg cells with a relaxation time of 150-200 s that remain stable after months of UV eposure was developed. These cells were used in the next generation of the Hg electric dipole moment (EDM) search and give about a factor of 2 higher statistical sensitivity compared to cells containing a mixture of CO and N2 gas.
