It is found that a measurement of this observable could yield vital information on the polarization of the light quark sea in the nucleon.4 pages, LaTeX, 2 figures included, Contribution to the proceedings of the "Future Physics at HERA"-workshop, DESY, Hamburg, 1995/96High Energy Physics - Phenomenologytext
