Abstract

A completely model-independent method of obtaining information on the spin using the quantum interference effect among various helicity states was proposed in a recent paper. Here we point out that this effect should be demonstrable in the existing data on e^-e^+ \to W^+ W^- at LEP-II and p \bar{p} \to Z^0 + j at Tevatron.
