Abstract The numerical model of the diffuse reflection of Gaussian beam from the surface of biological tissue is introduced. The two-dimensional fractional Brownian motion (fBm) with the Hurst index H and the scale parameter σ was used for the simulations of the tissue surface relief. For the surfaces described by fixed σ = 0.1 and H = 0.55, H = 0.803 (corresponds to the surface of a banana fruit), H = 0.9, the angular distributions of the reflected radiation intensity were calculated using a Kirchhoff integral approach. The resulting distributions considerably differ from each other. Therefore, the introduced model can be used for the solution of the inverse problem of finding the fBm parameters of tissue surfaces employing the experimentally measured distribution of the reflected radiation intensity.

The velocity distributions for the Cl(2P3/2) and Cl(2P1/2) photofragments produced by the photolysis of Cl2 at 308 nm are measured using ion imaging. The angular distributions yield anisotropy parameters of β(2P3/2)=−1.00±0.05,β(2P1/2)=−0.95±0.05, suggesting that Cl(2P3/2) and Cl(2P1/2) is essentially produced via non-adiabatic curve crossing between the lu and the 0u+ excited electronic states.
