Abstract
A particular class of Drinfel'd twists is constructed for any finite-dimens ional irreducible representation of the Yangian Y(sl(2)), by means of the f unctional Bethe ansatz technique for the XXX Heisenberg chain of arbitrary spins. These twists factorize the corresponding R-matrices in these represe ntations, and induce a new basis of the space of states of the chain, parti cularly convenient for the computation of correlation functions.
