| 英文摘要 | We investigate an idea of how to use analysis of bremsstrahlung photons to study the internal structure of a proton under nuclear reaction with a nucleus. A new model is constructed to describe bremsstrahlung emission of photons which accompanies the scattering of protons off nuclei. Our bremsstrahlung formalism uses a many-nucleon basis that allows us to analyze coherent and incoherent bremsstrahlung emissions. Because a scattered proton can be under the influence of strong forces and produces the largest bremsstrahlung contribution to the full spectrum, we focus on accurate determination of its quantum evolution in relation to the nucleus based on quantum mechanics. For this purpose, we generalize the Pauli equation with an interacting potential describing evolution of a fermion inside the strong field, including the electromagnetic form factors of nucleons based on deep inelastic scattering theory. Anomalous magnetic momenta of nucleons reinforce our motivation to develop such a formalism. The full bremsstrahlung spectrum in our model (after renormalization) is dependent on form factors of the scattered proton. In our calculations we choose the scattering of p + Au-197 at a proton beam energy of 190 MeV, where experimental bremsstrahlung data were obtained with high accuracy. We show that the full bremsstrahlung spectrum is sensitive to the form factors of the scattered proton. In the limit without such form factors, we reconstruct our previous result (where form factors of the scattered proton were not studied). |
