We present H-like Fe xxvi and He-like Fe xxv charge-exchange spectra resulting from collisions of highly charged iron with N _ { 2 } gas at an energy of \sim 10 eV amu ^ { -1 } in an electron beam ion trap . Although individual high- n emission lines are not resolved in our measurements , we observe that the most likely level for Fe ^ { 25 + } \rightarrow Fe ^ { 24 + } electron capture is n _ { max } \sim 9 , in line with expectations , while the most likely value for Fe ^ { 26 + } \rightarrow Fe ^ { 25 + } charge exchange is significantly higher . In the Fe xxv spectrum , the K \alpha emission feature dominates , whether produced via charge exchange or collisional excitation . The K \alpha centroid is lower in energy for the former case than the latter ( 6666 versus 6685 eV , respectively ) , as expected because of the strong enhancement of emission from the forbidden and intercombination lines , relative to the resonance line , in charge-exchange spectra . In contrast , the Fe xxvi high- n Lyman lines have a summed intensity greater than that of Ly \alpha , and are substantially stronger than predicted from theoretical calculations of charge exchange with atomic H. We conclude that the angular momentum distribution resulting from electron capture using a multi-electron target gas is significantly different from that obtained with H , resulting in the observed high- n enhancement . A discussion is presented of the relevance of our results to studies of diffuse Fe emission in the Galactic Center and Galactic Ridge , particularly with ASTRO-E2/Suzaku .
