We report on a study of the relative rates of B meson decays into psi(2S) andJ/psi mesons using 1.3 fb^-1 of pbar p collisions at sqrt(s) = 1.96 TeVrecorded by the D0 detector operating at the Fermilab Tevatron Collider. Weobserve the channels B^0_s -> psi(2S)phi, B^0_s -> J/psi phi, B^+/- -> psi(2S)K^+/-, and B^+/- -> J/psi K^+/- and we measure the relative branching fractionsfor these channels to be B(B^0_s -> psi(2S)phi)/B(B^0_s -> J/psi phi) = 0.55+/- 0.11 (stat) +/- 0.07 (syst) +/- 0.06 (B), B(B^+/- -> psi(2S) K^+/-)/B(B^+/--> J/psi K^+/-) = 0.65 +/- 0.04 (stat) +/- 0.03 (syst) +/- 0.07 (B) where thefinal error corresponds to the uncertainty in the J/psi and psi(2S) branchingratio into two muons.
