The ($\gamma$, $p$) Reaction on Light Nuclei in the $\Delta(1232)$ Resonance Region

Homma, S. ; Kanazawa, M. ; Koike, M. ; et al.

Phys.Rev.Lett. 53 (1984) 2536, 1984.

Inspire Record 203334 DOI 10.17182/hepdata.20403

Momentum spectra of protons from the (γ, p) reaction have been measured at θp=30° for H1, H2, He4, Be9, C12, and O16 with a tagged photon beam with energies from 187 to 427 MeV. By analysis of these inclusive proton spectra, cross sections for the pion photoproduction from the quasifree nucleon in the target nucleus and those for the photodisintegration of the quasifree two-nucleon system have been obtained as a function of the photon energy and of the target mass number.

On the Angular Dependence of Photoprotons From Nuclei Irradiated by $\gamma$ Quanta With Maximum Energy 4.5-{GeV}

Alanakian, K.V. ; Amarian, M.Dzh. ; Demirchyan, R.A. ; et al.

Nucl.Phys.A 367 (1981) 429, 1981.

Inspire Record 147184 DOI 10.17182/hepdata.18468

The angular dependences of proton photoproduction from the nuclei 12 C, 63 Cu and 208 Pb irradiated by bremsstrahlung γ-quanta with maximum energy 4.5 GeV, both in the cumulative region (i.e. in the kinematical region in which the production of protons in the collision of γ-quanta of the given energy with the quasi-free nuclear nucleon is forbidden) and in the non-cumulative region, are investigated. The experimental data obtained are compared with the results of theoretical calculations of cumulative proton photoproduction according to the following models: the “quasi-two-body” scaling model, the low-nucleon correlation model, the fluctuon model and the cluster model.
