SUMMARY:Rotational orientation effects in gas-surface collisions - Helen C
 hadwick\, Department of Chemistry\, The University of Swansea

DESCRIPTION:The interaction of hydrogen with surfaces plays a pivotal role
  in a range of applications\, from the safe storage of rocket fuel to hete
 rogeneous catalysis. One particular quantum-state which it was difficult t
 o control was the rotational orientation of the molecule\, which classical
 ly corresponds to whether the molecule is rotating like a helicopter or a 
 cartwheel as it approaches the surface. In my talk\, I will introduce a un
 ique magnetic molecular interferometry technique which allows us to contro
 l and manipulate this\, and demonstrate how it can be used to extract info
 rmation about how the amplitude and phase of the rotational wavefunction o
 f the molecules changes when they collide with the surface\, before presen
 ting an overview of the results that we have obtained using the technique.
