摘要: The FRAGM experiment at the ITEP-TWA heavy ion facility has a unique opportunity of measuring momentum distributions nuclear fragments. We present results 56 Fe fragmentation into light ions on 9 Be target 0.23 GeV/nucleon. spectra projectile like fragments were measured with high resolution beam line spectrometer. In contrast to carbon fragmentation, where have Gaussian-like shapes, in emission shapes double-humped structure. This splitting is most pronounced proton spectra. possibility describing this effect by asymmetric fission and multifragmentation discussed. A comparison made FRS measurements GSI. obtained experimental data are reasonable agreement predictions several transport codes such as BC, INCL LAQGSM.
