We performed inelastic neutron scattering experiments on [Ni(chxn) 2Br]Br2. Magnetic excitations peaked at 6 meV were observed at the magnetic zone center at 5 K, also, integrated intensity including quasielastic scattering showed a maximum at 35 K. These properties are consistent with the spin-Peierls state.
