Radiation Effects in Solid Nitrogen
Abstract
The radiation effects and relaxation processes in pre-irradiated by an electron beam solid N2 have been studied with a focus on the behavior of the so far unidentified emission band at 360 nm. The study was performed using optical and current spectroscopy methods: cathodoluminescence and developed by our group nonstationary luminescence, as well as spectrally resolved thermally stimulated luminescence, and thermally stimulated exoelectron emission. The measurements cover the temperature range of the α -phase existence. Activation spectroscopy evidenced connection of the 360 nm band with the neutralization reaction. Possible scenarios of N4+ neutralization via dissociative recombination are discussed, and interpretation of the 360 nm band is suggested.
