A preliminary measurement of the ratio of branching ratios BR(B{sup +} {yields} J/{psi}K{sup +})/BR(B{sup 0} {yields} J/{psi}K{sup 0}) and BR(B{sup +} {yields} J/{psi}K{sup +})/BR(B{sup +} {yields} J/{psi}K{sup *+}) is made by fully reconstructing each mode, where J/{psi} {yields} {mu}{sup +}{mu}{sup {minus}}, K{sup *+} {yields} K{sup 0}{sub s}{pi}{sup +} and K{sup 0}{sub s} {yields} {pi}{sup +}{pi}{sup {minus}}. The data were taken with the CDF detector during the 1993 run. The total integrated luminosity is {approx} 20pb{sup {minus}1} resulting in a sample of about 170 J/{psi}K{sup {+-}}, 50 J/{psi}K{sup 0}{sub S} and 25 J/{psi}K{sup *{+-}} candidate events. The results will be reported.
