Abstract
New GRAAL data on the fragmentation of carbon nuclei by photons at 800 - 1500 MeV are discussed. In addition to previously published results for the proton and neutron emission probabilities at different multiplicities, preliminary results on the yields of heavier fragments as d, t, 3 He and α -particles are presented. The obtained results are compared with theoretical predictions and other fragmentation data measured in different reactions induced by photons, electrons and relativistic ions.

New information is analyzed in terms of the dynamics of nuclear excitations and correlations of nucleons in nuclei
Summary
Motivation to study the nuclear fragmentation by photons at intermediate energies is caused by several reasons. That is a way to investigate the nuclear dynamics leading to the creation of nuclear clusters in the final state of interaction. Such projectiles as photons allow to describe the process qualitatively and to test the theoretical predictions [1] with high accuracy. We continue an analysis of the GRAAL data [3] devoted to the nucleon fragmentation of 12C nuclei to study nuclear fragments heavier than nucleons. One can see that all the fragments are created in the final state of interaction when a nucleus undergoes the transfer from the liquid to gas state
