The line shape of CⅥ 207.1nm has been measured with optical spectroscope multichannel analyzer on HT-6M Tokamak. The result of the analysis of line shape showed that CⅥ 207.1nm line emission arised mainly from the charge exchange-recombination processes. The temporal behavior of CⅥ line emission also proved this conclusion. The radial profile of C6+ ion has been deduced from the measurements of neutral hydrogen density and the volume emission coefficient of CⅥ 207.1nm line emission.
