✦ Synopsis

For the scattenng of He from C,H, a~ 73 meV &ffracUon undulauons m the angular dzstnbution of the total slgnal and the inelastic energy loss from ume-of-fight specm have been measured In the range of center-of-mass angles 3" < 9 c 65O The da:a are analyzed for the amsotropy of the repulswe potential by IWO complementary models rn whch the He atoms are treated ellher as wave packels or as &screte part~les W~lh a modified Fraunhofer model the observed dlffrnchon anomahes can be attnbuted to a rotauonally symmetnc elhpsord and provides urformauon on rhe senu-axis difference a -b A clawcal analysts ' Present address Fvma Valve RHW.
