【 摘 要 】

Synopsis We performed charge exchange collision experiments of metastable He-like C, N and O ions (1s2s3S1) with neutral target gases, and observed soft X-rays from doubly excited Li-like C, N and O ions produced by single electron capture. These emissions corresponded to 1s22s1S0- 1s2s (3S1) np transitions according to calculations for transition energies by the Cowan code.
