Root-Mean-Square Thickness of Tails

The segment density distribution q6(z) for a single tail of size i is given by Hesselink39,40 as 

Hesselink51 assumed that the conformation of macromolecules adsorbed on the interface consists of one train and two tails. The number of tails with i segments, n(i), is calculated from the partition function for the tail-train conformation, and the normalized segment density distribution p7(z) in tails is derived by methods analogous to those used in Hesselink s derivation of the segment density distribution in loops. The result is 

No analytical expression of the segment distribution for the loop-train-tail conformation has as yet been obtained.
