The effect of formation in a neon cryocrystal of atomic-type 2p<sup>5</sup>3s <sup>3</sup>P<sub>2</sub> centres obtained as a result of He gas discharge products being trapped in a growing neon cryocrystal is discovered. The unstable excited 2p<sup>5</sup>3s<sup>3</sup>P<sub>2</sub> states in the neon cryocrystal were detected by ESR. This effect is interpreted as a new phenomenon: quasi-resonance transfer of excitation energy from the metastable He 2<sup>3</sup>S<sub>1</sub> atom trapped in a growing neon cryocrystal to the exciton energy band of the neon crystal followed by the exciton self-trapping into the 2p<sup>5</sup>3p state and subsequent decay, ending in the 2p<sup>5</sup>3s <sup>3</sup>P<sub>2</sub> state recorded by ESR in our experiment. A temperature study showed that the rate constant lambda of the process of excitation energy transfer from the He 2<sup>3</sup>S<sub>1</sub> atom to the neon cryocrystal exciton band follows the Arrhenius-like law lambda - lambda <sub>0</sub> exp(-E/kT); the 'activation energy' E of the process turns out to be 0.0010(5) eV. |
