Book excerpt: This paper reports on the measurement of the polarization in the decay B[sup o] [yields] J/[psi]K[sup *o] using data collected at the collider Detector at Fermilab in [bar p]p collisions at [radical]s = 1.8 TeV. B[sup O] mesons were reconstructed through the decay chain B[sup o] [yields] J/[psi]K[sup *o], J/[psi] [yields] [mu][sup +][mu][sup [minus]], K[sup *o] [yields] K[sup +][pi][sup [minus]]. A sample of 50 [plus-minus] 11 events was used in the measurement, yielding the result [Gamma][sub L]/[Gamma] = 0.66 [plus-minus] 0.10 (stat) [sub [minus]]0.10 [sup +0.08] (sys).
