Abstract

The decays of the

ψ (2 S)

into vector plus tensor meson final states have been studied for the first time using the BES detector. We determine upper limits on branching fractions for

ψ (2 S)

decays into

ω f_{2}

ρ a_{2}

K^{* 0} {\bar{K}}_{2}^{* 0} + c . c .

, and

φ f_{2}^{'} (1525)

that are, in each case, significantly smaller than the corresponding branching fractions for the

J / ψ

meson, scaled according to the expectations of perturbative QCD.
