Differential cross sections for inelastic p 9Be scattering (to the J α = 1/2+ level) were calculated on the basis of Glauber’s diffraction theory. The wave function for the 9Be nucleus in the three-particle 2αn model was used in this calculation. An expansion of this wave function in a series in Gaussian functions and the representation of the Glauber operator Ω in the form conjugate to the three-particle wave function make it possible to calculate analytically inelastic-scattering matrix elements. The differential cross section calculated by using the 2αn wave functions agrees well with available experimental data at E = 180 MeV.
