Abstract: | We investigate inclusive photoproduction off complex nuclei, concentrating on the feasibility to examine a possible in-medium change of the properties by observing the invariant-mass spectrum. The simulations are performed by means of a BUU transport model including a full coupled-channel treatment of the final-state interactions. In-medium changes of the spectral density are found to yield a moderate modification of the observables as compared to the situa tion in free space. Also the effects of a momentum dependence of the strong potential are discussed.Received: 28 October 2003, Revised: 26 November 2003, Published online: 8 June 2004PACS: 25.20.-x Photonuclear reactions - 13.60.-r Photon and charged-lepton interactions with hadrons - 13.60.Le Meson production - 14.40.-n Mesons |
