Spatial Overlapping of Holes in Nuclear-Track Membranes with Different Angular Distributions

The results of Monte Carlo calculations on the relative number of spatially overlapping holes W _over in track membranes, depending on porosity P for possible angular distributions of ion incidence (pore orientation) are presented. The values of the relative number of overlapping pores in the bulk, W _m (m = 2, 3, ..., 10), were calculated and the relative hole overlap areas were determined. The choice of the most effective angular distributions for the manufacture of track membranes is discussed.
