N2 - The conditions during light emission from the fracture of solids have been difficult to determine because such mechanoluminescence (ML) is usually weak. When ML is produced by acoustic cavitation of a liquid slurry of resorcinol crystals, however, we observe bright light emission, which makes it possible to measure plasma conditions by emission spectra: a bimodal heavy atom emission temperature profile is observed with 405±22K (for 80% of emitting CH) and 4015±730K (for 20%), with an electron density and energy of 1.3±0.13×1014cm-3 and ∼3.5eV (i.e., an effective Te∼41000K).
