英文摘要	The measurement results on 200-1000nm excitation spectra of light from a solid surface of Ti which is excited by slow highly-charged ions(SHCI) Xe-126(q+) (6less than or equal toqless than or equal to30) with it kinetic energy of 150keV are reported. The results show that the characteristic spectral lines of the target atoms can be effectively excited by the SHCI even though the beam intensity of the incident ions is very weak (only about one per one nanosecond). We have also found that when the number of the peeled electrons of the projectile is beyond a critical value which depends on the properties of the target, about 20 for Ti, the spectral intensity of the characteristic spectral lines can be greatly enhanced. Theoretical analyses show that this phenomenon is closely related to the surface plasmon excitation of the free electron gas of the metal surface during the potential energy release of the single-electron transfer when the number of the peeled electrons is beyond the critical value.
