A comparative study of anti-resonance effects in InSe and InSe doped with GaS, using the resonant Raman spectroscopy is presented. The nonpolar optical phonon of  symmetry in InSe exhibits a pronounced decrease in the Raman cross-section at excitation energy 2.585 eV. In InSe doped with GaS samples, it is found that the anti-resonance behavior decreases as doping contents are increased. To acco...

Most image reconstruction algorithms for biomedical photoacoustic tomography make the assumption that the optically-generated ultrasonic waves are recorded by pressure detectors with an omni-directional response. In other words, the detectors are assumed to sample the pressure field exactly at a point. In practice this is rarely the case as real detectors have a finite size and often respond no...

We present a model-independent study aimed at characterising the nature of possible resonances in the jetphoton or jet-Z final state at hadron colliders. Such resonances are expected in many models of compositeness and would be a clear indication of new physics. At leading order, in the narrow width approximation, the matrix elements are parameterised by just a few constants describing the coup...

The change of elastic constants and mechanical loss from [loo] elastic dipoles are calculated on the basis of a six level tunneling model. Resonance and relaxation mechanisms are treated together, and expressions for Cfand C11sound modes are given. The results are used to analyse experimental data for the RbC1:OH system. The low temperature ultrasonic attenuation is attributed to the resonance ...
