The interaction between highly charged ions (HCIs) and the solid surface causes various phenomena due to high potential energy of HCIs. Luminescence is also included in them. In order to investigate the origin of the light emission from the surface irradiated with HCIs, we conducted spectroscopic measurements and then we investigated characteristics of Balmer light emission because potential effect of HCI was remarkable in Balmer light emitted from hydrogen atoms desorbed from the surface. In the present study, the Balmer light intensity was revealed to increase rapidly with the charge state of HCIs.
