The measurement of light spectrum of NiⅠand NiⅡwith wavelengths from 200 to 1 000nm emitted from the solid surface of Ni, which is excited by slow highly char ged ions 126Xe30+is reported. The result shows that the chara cteristic spectral lines from transitions between complex configurations of atom s and ions can be effectively excited by the impact of highly charged ions on a solid surface even though the ionic beam is very weak. The result shows especia lly that the characteristic spectral lines from forbidden transition (M1and E2) of NiⅠand NiⅡcan be effectively excited.
