N2 - We have observed a linear pressure dependence of longitudinal relaxation time T1 at 4.2 and 295 K in gaseous He3 cells made of either bare Pyrex glass or Cs- or Rb-coated Pyrex due to paramagnetic sites in the cell wall. The paramagnetic wall relaxation is previously thought to be independent of He3 pressure. We develop a model to interpret the observed wall relaxation by taking into account the diffusion process, and our model gives a good description of the data.
