We present a measurement of the time-dependent asymmetry in the rate for {anti }B{sup 0}{sub d} versus B{sup 0}{sub d} decays to J/{psi} K{sup 0}{sub S} . In the context of the Standard Model this is interpreted as a measurement of the CP-violation parameter sin(2{beta}). A total of 198 {+-} 17 B{sup 0}{sub d}/{anti B}{sup 0}{sub d} decays were observed in p{anti p} collisions at ps = 1:8 TeV by the CDF detector at the Fermilab Tevatron. The initial b-flavor is determined by a same side avor tagging technique. Our analysis results in sin(2{beta}) = 1:8 {+-} 1:1(stat) {+-} 0:3(syst).
