Treloar's distribution and its numerical implementation

A simple derivation ot Treloar's distribution Wz(h) for the length h of a freely connected chain made up from Z-1 bonds of the length b is given on the basis of Chandrasekhar's integral form. The recurrence equations derived from an integral form and also from that of Treloar allow successive computations of the distributions Wz. These equations were used for numerical calculations of Wz for all Z <or=800 and proved to be very efficient. The course of several distributions is presented.
