Abstract: In this paper the formulae of the collision probobilities for the isotro-pic two-dimensional neutron transport problem on the mixed region consisting of rectangular or triangle cells are given. Based on these formulae the code has been developed and applied to tow-dimensional mixed cells calculations. The calculated results show good agreement with those of Montecalo method and conservation principles.
