Extension of the LAQGSM03.01 Code to Describe Photo-Nuclear Reactions up to Tens of GeV

Abstract

The Los Alamos version of the Quark-Gluon String Model implemented in the code LAQGSM03 was extended to describe photonuclear reactions at energies up to tens of GeV. We have incorporated 56 channels to consider gamma+p elementary interactions during the cascade stage of reactions and 56 channels for gamma+n interactions, in addition to absorption of photons on two-nucleon pairs, into LAQGSM03 and have tested the extended code referred to as LAQGSM03.01 on a number of measured high-energy photonuclear reactions. Here, we present the photonuclear reaction model of LAQGSM03.01 and show examples of its results compared with available experimental data.
