Abstract

For the first time the direct method of detection of intranuclear clusters of nuclear matter was developed. This method is based on the unique kinematic features of elastic scattering of identical particles and heavy accelerated particle on the light target nucleus. The specified uniqueness, as is shown by the authors, consists in that angular distribution of elastically scattered α-particles in the laboratory system in the case of the scattering of identical particles is limited to θlab=900, and the scattering of heavy particles on light target nucleus is limited by the critical angle θlab<900. The method unequivocally proved their spatial localization in the volume of the nucleus. The uniqueness of the method consists also in the fact that in one experiment all intranuclear clustered amplitudes are measured. The method is shown on absolute coincidence of kinematics for the clusters inside the nucleus, and light target nuclei in the form of free microparticles.
