### Abstract

To determine J^{π} values of the pair of states at 8.89 MeV in ^{10}B given so far as 2^{+} and 3^{(-)}, we have investigated the ^{9}Be(p, α_{2}γ)^{6}Li reaction, which selects the natural parity states. We have deduced the (p, α_{2}) angular distribution at 17 energy points from the measured Doppler-broadened γ-line shapes. We have found a 2^{+} and a 3^{-} resonance and determined their parameters by a two-level multi-channel R-matrix fit. The energies and widths obtained are about the same as those from the ^{9}Be(p, n)^{9}B and earlier (p, γ) measurements. On this basis, the levels found in our (p, α_{2}) measurement and in the (p, n) reaction are assumed to be identical and the resonance parameters derived from them have been used to predict the ^{9}Be(p, p)^{9}Be elastic scattering cross sections. The calculated curve reasonably agrees with our measured elastic excitation functions.
