英文摘要	In this paper, we report visible light emission from 320 keV Krq+ (4 <= q <= 9) ions on the Cu target. The wavelength range measured is from 300 nm to 656 nm. Two Cu I spectra deriving from different initial states and one Kr I line are detected. Specifically, the two Cu I lines belong to transitions 3d(10)4p (P-2(3/2)0) - 3d(10)4s- (S-2(1/2)) at 324.78 nm (A) and 3d(10)4p(P-2(3/2)0) - 3d(10)4s- (S-2(1/2)) at 327.42 nm (B), respectively, and the photon yield ratio of spectra lines (A) and (B) are about 2:1. The Kr I line belongs to transition 4s(2)4p(5)(P-2(3/2)0)11d (2)[3/2](0) - 4s(2)4p(5)(P-2(3/2)0)5P (2)[1/2] at 486.12 nm (C). In addition, the experimental results show that the photon yields of all lines are increasing with the charge state increase. (C) 2017 Elsevier B.V. All rights reserved.
