Observation of crystallization of amorphous solid water under the conditions of secondary emission mass spectrometric experiments
A phenomenon of termination of sputtering of protonated water clusters (H2O)nH⁺ in low-temperature secondary emission mass spectrometric studies of solid water was observed in the temperature range of crystallization of amorphous solid water (ASW). In this range the mass spectra contained only H₃O⁺,...
