1.88 GeV/n Fe beams of LBL were vertically irradiated to the chambers com-posed of a pile of plastic track detector (CR-39) and nuclear emulsion plates.The charge number of projectile fragments in Fe interactions was carefully ex-amined by use of CR-39. The angular distributions of emitted alpha particles havebeen investigated for several ranges of charge numbers of j>rojectile fragments.The result of analysis shows that the omission angle distribution of alpha particlesat large angles cannot be explained by the single mechanism of the fragmentationfrom a clean cut spectator. For events of central collisions with smaller chargesof projectile fragments, the effective temperature for the production of alphaparticles turns out to be much higher than that of the evaporation theory. Theresults are applied to the calibration of primary energy estimation by the openingangles of alpha particles.
