We present a measurement of the time-dependent asymmetry in the rate for {ovr B}{sup thinsp0}{sub d} versus B{sup 0}{sub d} decays to J/{psi}K{sup 0}{sub S} . A nonzero asymmetry would be an indication of CP violation, and within the standard model this may be used to measure the CP -violation parameter sin(2{beta}) . A total of 198{plus_minus}17 B{sup 0}{sub d}/{ovr B}{sup thinsp0}{sub d} decays were observed in p{ovr p} collisions at {radical} (s) =1.8 TeV by the CDF detector at the Fermilab Tevatron. B{sup 0}{sub d} and {ovr B}{sup thinsp0}{sub d} are distinguished by a technique based on charge correlations from hadronization of the b quark. Our analysis results in sin(2{beta})=1.8{plus_minus}1.1(stat ){plus_minus}0.3(syst) . {copyright} {ital 1998} {ital The American Physical Society }
