“…Figure 2 shows the b ik distribution (1) for the fragmentation channel 22 Ne → nα for n equal to 3 (240 events), 4 (79 events), and 5 (10 events) which is rather narrow. The distribution "tails" appear to be due to the 4 He diffractive scattering or 3 He formation proceeding at higher momentum transfers. The events, satisfying the non-relativistic criterion b ik < 10 −2 for each α-particle pair were selected for n equal to 3 (141 events), 4 (47 events), and 5 (6 events).…”

“…Like the process 12 C → 3α, this dissociation can be considered as a visible reflection of the inverse process of a ternary N ws He fusion. It can provide a significantly higher energy output followed by 4 He pair production. Search for a ternary 3 He process appears to be a major goal of further accumulation of statistics.…”

“…Experimental data on the charged topology for the final states of a number of light nuclei have been described in [2,3,4,5,6]. More specific studies were performed for the leading channels like 12 C → 3α [7], 16 O → 4α [8,9], 6 Li → dα [10,11], 7 Li → tα [12], 10 B → dαα [13], and 7 Be → 3 Heα [14].…”

Abstract. The relativistic invariant approach is applied to analyzing the 3.3 A GeV 22 Ne fragmentation in a nuclear track emulsion. New results on few-body dissociations have been obtained from the emulsion exposures to 2.1 A GeV 14 N and 1.2 A GeV 9 Be nuclei. It can be asserted that the use of the invariant approach is an effective means of obtaining conclusions about the behavior of systems involving a few He nuclei at a relative energy close to 1 MeV per nucleon. The first observations of fragmentation of 1.2 A GeV 8 B and 9 C nuclei in emulsion are described. The presented results allow one to justify the development of few-body aspects of nuclear astrophysics.PACS. 21.45.+v Few-body systems -23.60.+e α decay -25.10.+s Nuclear reactions involving few-nucleon systems

Possibilities of the nuclear emulsion technique for the study of the systems of several relativistic fragments produced in the peripheral interactions of relativistic nuclei are discussed. The interactions of the 10 B and 9 Be nuclei in emulsion are taken as an example to show the manifestation of the cluster degrees of freedom in relativistic fragmentation. For the case of the relativistic 9 Be nucleus dissociation it is shown that exact angular measurements play a crucial role in the restoration of the excitation spectrum of the alpha particle fragments. The energy calibration of the angular measurements by the 9 Be nucleus enables one to conclude reliably about the features of internal velocity distributions in more complicated systems of relativistic α particles.
