Abstract
The calculation of the differential cross section of the inelastic p9Be scattering (to the levels J = 1/2, 3/2) was made in the framework of the Glauber diffraction theory. We used the wave function of 9Be in the ground and excited states in the three-body 2alpha-n model. Expansion in series by gaussoids of the wave function of 9Be and presentation of the Glauber operator in the form, conjugated with three-body wave function, allow us to calculate analytically the matrix elements of inelastic scattering, taking into account all of the multiplicities of scattering and rescattering on clusters and nucleon, that are the components of 9Be. The drawn up profiles of excited state functions allow us to make conclusion on their extended neutron distributions. The differential cross section with the wave function in model 1 (with the alpha-alpha-Ali-Bodmer potential) is in a good agreement with available experimental data at E = 180 MeV.
