  We present a new method to study light scattering on non-absorbing spherical
particles. This method is based on the Ramsauer approach, a model known in
atomic an nuclear physics. Its main advantage is its intuitive understanding of
the underlying physics phenomena. We show that although the approximations are
numerous, the Ramsauer analytical solutions describe fairly well the scattering
phase function and the total cross section. Then this model is applied to the
Henyey-Greenstein parameterisation of scattering phase function to give a
relation between its asymmetry parameter and the mean particle size.
