FIG. 5.

Angular resolved energy transfer probability density functions. The thick black line represents near forward scatterings , the thin black line represents sideway scattering , and the thick gray line represents backward scatterings . In the left column, the sideway and backward scatterings have been multiplied by some factors, respectively, such that they and forward scattering have the same value at . In the right column, they are plotted in the same scale.
