      abstract     = {Absorption, excitation and luminescence spectra of pure and
                      Eu doped CsI crystals were studied depending on the
                      activator content, excitation energy, heat treatment and
                      X-ray irradiation. Several types of Eu2+ related centers
                      were found. It is shown that complex centers are stable at
                      room temperature but their structure and concentration
                      changes at heat treatment and under irradiation. The
                      increased content of oxygen-containing radicals was
                      determined by IR spectroscopy in Eu-containing crystals as
                      opposed to pure one. It is supposed that some of emission
                      centers in CsI:Eu are caused by the presence of intrinsic
                      (vacancy type) and extrinsic (oxygen or hydroxyl ions)
                      defects located in the nearest environment of Eu2+ ions.},
