Azimuthal using shadow cone

Azimuthal Angle Scan Using Shadow Cone... 

Figure 3.3.23 The azimuthal dependence of the negative ion recoil spectra for an incident angle of 17.5° and a recoil angle of 35° using a 2 keV Ne projectile. Each energy spectrum is over the range 0.5 < E/Eq < 1-0. The increase in ion yield as the oxygen emerges from the shadow cone of the neighbouring Ni atoms is evident from 15° to 35° [11].
