“…In the studies of our group that were reported in [19,20], it was shown that the mean multiplicities and various kinematical features of light mirror nuclei of 3 Н and 3 Не produced in 16 Оp collisions at a projectile momentum of 3.25 GeV/c per nucleon proved to be identical. This led to the conclusion that the kinematical conditions of their formation are similar.…”

“…The present study is a continuation of a series of investigations into the problem of the production of light fragments in 16 Оp collisions at a projectile momentum of 3.25 GeV/c per nucleon and aims at a comparative analysis of the properties of inclusive reactions involving the yield of deuterons and tritons. Here, we study the mean multiplicities of various isotopes having mass numbers in the range of A = 1-4, charged pions, and recoil protons, as well as the mean multiplicity and charge for the group of fragments that have a charge in the range of z = 3-7 and which accompany the formation of 2 Н and 3 Н triggering nuclei.…”

“…The data sample analyzed in the present study was taken from an ensemble of 8712 fully measured 16 Оp events. In order to perform a mass identification of fragments, we introduced the following intervals of laboratory momenta: singly charged fragments of momentum in the regions of 1.75 p 4.75 GeV/c, p = 4.75-7.75 GeV/c, and p > 7.75 GeV/c were treated as protons, deuterons ( 2 Н), and tritons ( 3 Н), respectively; doubly charged fragments of momentum in the regions of p < 10.75 GeV/c and p 10.75 GeV/c were classed with, respectively, 3 Не and 4 Не nuclei; triply charged fragments of momentum in the regions of p < 21.1 GeV/c, 21.1 p 24.35 GeV/c, and p > 24.35 GeV/c were associated with, respectively, 6 Li, 7 Li, and 8 Li nuclei; quadruply charged fragments of momentum in the regions of p < 24.35 GeV/c and p 24.35 GeV/c were taken to be, respectively, 7 Ве and 9 Ве nuclei; quintuply charged fragments of momentum in the regions of p < 34.1 GeV/c and p 34.1 GeV/c were identified as, respectively, 10 В and 11 В nuclei; and sextuply charged fragments of momentum in the regions of p < 34.1 GeV/c, 34.1 p 37.35 GeV/c, and p > 37.35 GeV/c were thought to be, respectively, 10 C, 11 С, and 12 С nuclei.…”

Comparative analysis of properties of channels of deuteron and tritium production in 16Op collisions at a projectile momentum of 3.25 GeV/c per nucleon

The results of a comparative analysis of channels involving the inclusive production of deuterons and tritons in 16 Оp collisions at a projectile momentum of 3.25 GeV/c per nucleon are presented. The mechanisms governing proton, deuteron, and triton production in the fragmentation of oxygen nuclei are found to be independent. It is shown that the observed proton-multiplicity correlations are associated predominantly with the character of the primary event of a proton-nucleon collision in 16 Оp interactions. It is found that, in reactions involving triton production, the contributions of processes leading to an increase in the mean proton multiplicity (n → p + π − and np → pn) and processes leading to its decrease (p → n + π + ) compensate each other.

These lecture notes present the capabilities of relativistic nuclear physics for the development of the physics of nuclear clusters. Nuclear track emulsion continues to be an effective technique for pilot studies that allows one, in particular, to study the cluster dissociation of a wide variety of light relativistic nuclei within a common approach. Despite the fact that the capabilities of the relativistic fragmentation for the study of nuclear clustering were recognized quite a long time ago, electronic experiments have not been able to come closer to an integrated analysis of ensembles of relativistic fragments. The continued pause in the investigation of the "fine" structure of relativistic fragmentation has led to resumption of regular exposures of nuclear emulsions in beams of light nuclei produced for the first time at the Nuclotron of the Joint Institute for Nuclear Research (JINR, Dubna). To date, an analysis of the peripheral interactions of relativistic isotopes of beryllium, boron, carbon and nitrogen, including radioactive ones, with nuclei of the emulsion composition, has been performed, which allows the clustering pattern to be presented for a whole family of light nuclei.
