Abstract
Recombining plasma x-ray laser using charge exchange recombination (CXR) is proposed. Fully stripped carbon ions collide with neutral He atoms and become excited hydogenlike carbon ions, in which the excited levels with n = 3 or 4 are mainly populated. We calculated the gain coeficients of the Balmer [MATH] and Lyman [MATH] lines of the hydrogenlike carbon ions by the use of a collisional-radiative model in which the CXR process is included. The calculated result shows that substantial gain can be generated for the Lyman [MATH] and Balmer [MATH] lines and that the gain of the Balmer [MATH] line can be strongly enhanced by the effect of CXR. We also report a preliminary experiment of this scheme
