Low density solid ozone

We report a very low density ( ∼ 0.5 g ∕ cm 3 ) structure of solid ozone. It is produced by irradiation of solid oxygen with 100 keV protons at 20 K followed by heating to sublime unconverted oxygen. Upon heating to 47 K the porous ozone compacts to a density of ∼ 1.6 g ∕ cm 3 and crystallizes. We u...

Description
Summary:We report a very low density ( ∼ 0.5 g ∕ cm 3 ) structure of solid ozone. It is produced by irradiation of solid oxygen with 100 keV protons at 20 K followed by heating to sublime unconverted oxygen. Upon heating to 47 K the porous ozone compacts to a density of ∼ 1.6 g ∕ cm 3 and crystallizes. We use a detailed analysis of the main infrared absorption band of the porous ozone to interpret previous research, where solid oxygen was irradiated by UV light and keV electrons.
