Forward Elastic Scattering of Light on Light , γ + γ → γ + γ
The forward elastic scattering of light on light, i.e., the reaction γ + γ → γ + γ in the forward direction, is analyzed utilizing real analytic amplitudes. We calculate ργγ , the ratio of the real to the imaginary portion of the forward scattering amplitude, by fitting the total γγ cross section data in the high energy region 5 GeV ≤ √ s ≤ 130 GeV, assuming a cross section that rises asymptoti...
متن کاملBacteria Size Determination by Elastic Light Scattering
Light extinction and angular scattering measurements were performed on three species of bacteria with different sizes and shapes (Pseudomonas aeruginosa, Staphylococcus aureus, and Bacillus subtilis). The Gaussian Ray approximation of anomalous diffraction theory was used to determine the average bacteria size from transmission measurements. A rescaled spectra combining multiple angular data wa...
متن کاملRaman signal enhancement via elastic light scattering.
The enhanced generation of a spontaneous Raman signal by way of elastic scattering is demonstrated. Using Monte Carlo simulations, we show that elastic scattering, by increasing the path length of light through the medium, enhances the generation of a Raman signal. This is investigated over a large parameter space, demonstrating that this effect is robust, and providing additional physical insi...
متن کاملCoupled Dipole Simulations of Elastic Light Scattering on Parallel Systems
The Coupled Dipole method is used to simulate Elastic Light Scattering from arbitrary shaped particles. To facilitate simulation of relative large particles, such as human white blood cells, the number of dipoles required for the simulation is approximately 105 to 106. In order to carry out such simulations, very powerful computers are necessary. We have designed a parallel version of the Coupl...
