An algorithm is presented for the evaluation of the even moments of the end
-to-end separation of a polymer chain. The only assumption made in the dist
ribution function is that the energy of the chain depends only on the indiv
idual bond lengths of the chain. This assumption covers many of the commonl
y used distribution functions. (C) 1999 American Institute of Physics. [S00
