N2 - Resonant coherent excitation and its radiative deexcitation were studied for hydrogen-like heavy ions axially channeled in a single crystal. The 6th order resonance for Ne9+ ions along the 〈111〉 axis of a gold crystal was found at the incident energy of 88 MeV by measuring the charge state distribution after passing through the crystal. The intensity of the Ne9+ Kα X-ray (1.02 keV) normalized to the Au M X-rays was measured for the 〈111〉-aligned and random directions of the incident beam. An enhancement in the Ne9+ deexcitation X-rays at the resonance was detected for the first time.
