Abstract: In the interest of studying cell membrane interactions with proteins in solution, we use small angle neutron scattering to probe the cell membrane. Small angle neutron scattering proves to be particularly convenient for this task because neutrons scatter readily from hydrogen-rich biological matter. A typical problem in scattering experiments is recovering the lost phase information of the scattered wave. Current methods for modeling the scattered intensity lose the phase information, which creates difficulties in inferring what is happening at the cell membrane. To improve these methods, we propose implementing fast Fourier transform algorithms and taking advantage of symmetries in the problem to improve the computational speed.
