DESCRIPTION:Speakers: Irina Zarubina (JINR)\nIn spite of the fact that nuc
 lear track emulsion (NTE) was developed more half a century ago\, it still
  remains a universal and cost-efficient detector. The application of NTE i
 s especially well grounded where tracks of nuclear particles cannot be rec
 onstructed using electronic detectors. At the JINR Nuclotron the BECQUEREL
  experiment [1] is performed a program of irradiation of NTE stacks in the
  beams of relativistic isotopes of beryllium\, boron\, carbon and nitrogen
 \, including radioactive ones to study their cluster structure. Сharge-to
 pology distributions of final states have an individual character appearin
 g to be some kind of a signature of the isotope under study. The NTE techn
 ique allows one to observe the 3D images of few-body ensembles originated 
 in peripheral collisions and explore the fragmentation of the relativistic
  nuclei down to the most peripheral interactions - nuclear “white”star
 s [2].\nThe competitive character of the novel NTE is proved in measuremen
 ts of slow α particles and heavy ions (summarized in [3]). The possibilit
 y of α spectrometry was verified and the atom drift effect is established
  in measurement of decays of 60 MeV 8He nuclei implanted in NTE [4]. Corre
 lations of α particles in splitting of 12C nuclei by 14.1 MeV neutrons [5
 ] as well as 7Li and 4He nuclei produced in 10B breakup by thermal neutron
 s in boron-enriched NTE [6] are studied. NTE samples were irradiated with 
 slow Kr and Xe ions [7\,8]. Surface irradiations of NTE samples were perfo
 rmed with automatic movement of the 252Cf source [9].Thus\, the connection
  of high energy and low energy nuclear physics appears. Classic observatio
 ns of fundamental importance presented in “The Study of Elementary Parti
 cles by the Pho-tographic Method”by C. H. Powell\, P. H. Fowler and D. H
 . Perkins can serve as a model of clarity in our time. Our research is imp
 lemented in keeping with this tradition by state-of-art means. The rich co
 llection of videos and images of the nuclear few-body processes gathered a
 t the Web site is presented [1]. In terms of applications they are relevan
 t for the development of advanced systems of automatic search for nuclear 
 interactions\, as well as for university education.\n\nReferences\n1.	The
