The light spectrum of a wavelength from 200 to 1 000 nm emitted from Ti-atoms sputtered from the solid surface of Ti-target by slow highly charged ions (SHCI) has been done on the atomic physics experimental setup at the lab of ECRIS (14.5 GHz) in IMP (shown in Fig.1). The result shows that the atoms of the solid material can be strongly excited by the SHCIs even though the intensity of the incident ions is lower as
