Surface-induced transitions between Zeeman sub-levels of metastable neon
atoms traversing a micro-slit copper grating are investigated. The
quadrupolar part of the surface van der Waals interaction suddenly perturbs
the evolution of the Zeeman sub-levels in a magnetic field 
,
giving rise to van der Waals - Zeeman transitions. Exothermal inelastic transitions are
identified by the related deflection γ. In a diagram (γ,
the location of the inelastic peaks is fitted by straight lines
of slopes proportional to 
, where 
is the
magnetic number change.
