The main mechanism for the scattering of light by the interstellar medium is Mie scattering. This mechanism dominates when the scattering bodies are comparable to the wavelength of the light. Scattering by bodies much smaller than the wavelength of the light is fairly simple to model, and is given by the Rayleigh formula. In this regime the scattering is ...


For those wondering, to find the total number detected over some time period: Let the number incident/unit time = $N_I$, and the number detected/unit time = $N_D$ We need to consider the number of gold nucleons per unit area in the target. To find this we do: $\rho \over m_{Au}$ The flux of the incident particles, $J$ is simply $J$ = $N_I$ Let the ...
