About 1% or more of iron was introduced into a hydrogen-filled theta pinch by a guninjection method. The Fe x density in the plasma was determined from the measured intensity of the Fe x forbidden (coronal) line at 6374.5 Å. Electron collisional excitation rate coefficients for Fe x were obtained from measurements of Fe x vacuum-ultraviolet line intensities, electron density and temperature, and Fe x density. The experimental rate coefficients are compared with theoretical results.
