Abstract

He I and He II photoelectron spectra for N₂ adsorbed on W (110) have been measured at three different polar emission angles. The behaviour of the adsorbate-induced features with angle is compared to the angle- dependence of dipole matrix elements for oriented N₂, Ni-N₂, and Ni₉-N₂ clusters obtained by SCF-Xa-SW calculations. The agreement is very good for He I and acceptable for He II, if the N₂ axis is assumed normal to the “surface” and the assignment of peaks proposed earlier is used. For He II the use of the big cluster is important to arrive at good agreement.
