| Abstract: | The excitation processes in collisions between N6+ and He have been investigated by using the ECR ion source and the LHT-30 VUV Monochromator. The emission spectra shows that there are three channels of excitation in the N6+ and He collision system: (1) Single-electron capture into excited states. (2) Double-electron capture into excited states. (3) Direct excitation of indicident ions. |
