Abstract

We present new data on the $η^{'}$ meson based on 1414 $η^{'}$ events obtained from a 1 100 000-picture exposure of the BNL 31-inch hydrogen bubble chamber to a 2.18-GeV/c $K^{-}$ beam. We have measured the $η^{'}$ mass, width, and branching ratios. We find that the very-forward-produced $η^{'}$ mesons have anisotropic angular distributions with respect to the incident $K^{-}$ beam, suggesting that possibly $J^{PC} = 2^{- +}$ ; however, the standard Dalitz-plot analyses favor $J^{PC} = 0^{- +}$ over $2^{- +}$ .
