Influence of various gases on the intensity of single bubble sonoluminescence has been studied. The gases used were air, oxygen, nitrogen, argon and helium. Among these oxygen gave the brightest intensity with nitrogen giving the least. K e y w o r d s . Sonoluminescence; bubble dynamics PACS Nos 78.60; 43.25; 42.50 Single bubble sonoluminescence (SBSL) [1, 2] is the phenomenon of light emissio...

We present a link between the theory of deep water waves and that bubble surface perturbations. Theory correspondence is shown analytically for small wavelengths in linear regime investigated numerically nonlinear regime. To do so, we develop second-order spatial perturbation equations Rayleigh-Plesset equation solve them numerically. Our code publicly available. Studying capillary on stable bu...

Based on accurate Lennard-Jones-type interaction potentials, we derive a closed set of state equations for the description of warm atomic gases in the presence of ionization processes. The specific heat is predicted to exhibit peaks in correspondence to single and multiple ionizations. Such kinetic analog in atomic gases of the Schottky anomaly in solids is enhanced at intermediate and low atom...
