MAXIMUM-ENTROPY FOR HALF-SPACE ENERGY ALBEDO

The maximum entropy method is used to find the energy albedo for half- space, i.e., the classical albedo problem but extended to include ener gy dependence. The slowing-down kernel is described by elastic scatter ing and various model representations for dealing with anisotropic sca ttering. The energy albedo for different values of secondary particles per collision C is calculated and compared with exact and variational values given by Williams and Pade's approximant given by Machali et a l. (1981). Also the energy albedo for different mass-ratios is found a nd compared with Williams and Pade's results.
