Abstract
The effect of transverse magnetic gradients in Stern-Gerlach atom inte rferometry is to make interfere plane waves the momenta of which diffe r in their directions. As a result the contrast of the interference pa ttern produced by the longitudinal gradient is attenuated by an angula r autocorrelation function in the momentum space. This effect is studi ed experimentally on a thermal beam of metastable H (2s) atoms, with a radial transverse gradient (atomic ''axicon'').
