Abstract We report the observations of the decays B{sup +}{r_arrow}{psi}(2S)K{sup +} and B{sup 0}{r_arrow}{psi}(2S)K{sup {asterisk}}(892){sup 0} in p{bar p} collisions at a center-of-mass energy of 1.8 TeV using a 110thinsppb{sup {minus}1} data sample recorded by the Collider Detector at Fermilab. We also reconstruct the decays B{sup +}{r_arrow}J/{psi}K{sup +} and B{sup 0}{r_arrow}J/{psi}K{sup {asterisk}}(892){sup 0} and measure the six ratios of branching fractions of these four decays. The relative branching-fraction results are shown to be consistent with phenomenological factorization calculations of hadronic B-meson decays. We use the world-average branching fraction B(B{sup +}{r_arrow}J/{psi}K{sup +}) to derive B{bold (}B{sup +}{r_arrow}{psi}(2S)K{sup +}{bold )}=(0.56{plus_minus}0.08{plus_minus}0.10){times}10{sup {minus}3}, B{bold (}B{sup 0}{r_arrow}{psi}(2S)K{sup {asterisk}}(892){sup 0}{bold )}=(0.92{plus_minus}0.20{plus_minus}0.16){times}10{sup {minus}3}, and B{bold (}B{sup 0}{r_arrow}J/{psi}K{sup {asterisk}}(892){sup 0}{bold )}=(1.78{plus_minus}0.14{plus_minus}0.29){times}10{sup {minus}3}, where the first and second uncertainties are statistical and systematic, respectively. {copyright} {ital 1998} {ital The American Physical Society}
