摘要：

Polarization in the exclusive decay B --> J/PHIK* was measured using the ARGUS detector at the e+e- storage ring DORIS II. The ratio of the transverse to the total decay width was found to be GAMMA(T)/GAMMA = 0.03+/-0.16+/-0.15. This measurement demonstrates that the B0 --> J/PHIK*0 decay channel can be effectively used for CP violation studies.
