The problem of the beginning of motion of a cut in a plane under symmetric external loading is considered. The material lying
on the cut continuation forms a layer (interaction layer). A transition to a plastic state within the layer is assumed to
be possible. The behavior of the layer is described by an ideally elastoplastic model, and the plane outside the layer is
assumed to be linearly elastic. A system of boundary integral equations for determining the stress-strain state is derived.
Based on this system, a discrete model of separation of the layer material is constructed under the assumption of a constant
stress-strain state in the element of the interaction layer. The distribution of stresses in the pre-fracture zone is determined.

Results are presented from a study of 3184 six-prong π?p interactions at 5 GeV/c in the Dubna 1 m hydrogen bubble chamber. Cross sections for the various reaction channels are given and their energy dependence is discussed. The emphasis of this paper is on exhibiting the semi-inclusive particle spectra is sufficient detail so that it will be possible to use it for testing models and developing new concepts. In particular, invariant distributions are plotted against the scaled longitudinal momentum x, the rapidity y and the longitudinal momentum pL in the lab system. The net charge per x as well as y interval is also presented. It is found that the isotropic pion component is inconsistent with the Bose-Einstein formula. Comparison with data at other energies is made whenever possible. 相似文献

A phenomenological analysis of the channels of the production of three and four alpha particles in 16Op collisions at 3.25 GeV/c per nucleon is performed for the first time under conditions of 4π geometry. The experimentally observed azimuthal asymmetries and collinearity are described on the basis of a phenomenological model that assumes that the excitation of the nucleus involved is peripheral and that its decay is statistical. It is shown that the azimuthal asymmetries in question are due to the transverse motion of the fragmenting nucleus. The mean transverse momentum of alpha particles and the collinearity of their emission in the reaction plane are found to be independent of the transverse-momentum transfer to the nucleus involved. 相似文献

The momentum features of protons originating as fragments from 16Op interactions at 3.25 GeV/c per nucleon are analyzed for the first time under conditions of 4π geometry. It is found that the mechanisms of the production of all protons traveling in the forward direction in the rest frame of the fragmenting nucleus (with the exception of evaporated protons) do not depend on either the primary energy or the target-nucleus type, this regularity being quite universal for the formation of such protons. It is shown that there is a strong correlation between the shape of the momentum spectrum of protons appearing as fragments from such interactions, especially slow protons, and the degree of the excitation of the fragmenting nucleus. 相似文献

The differential cross section (dσ/dt) for the dp → ppn charge retention reaction at 3.3 GeV/c deuteron momentum is studied and compared with the Glauber multiple scattering theory. Within the limits of the uncertainties of the existing elementary nucleon-nucleon data, the simple Glauber model calculations give, in general, a fair agreement with experiment, except for the low |t| region where possible spin effects may play a role. 相似文献

The results obtained by studying the production of six-nucleon systems and nuclei that is accompanied by the yield of charged pions in 16Op collisions at a momentum of 3.25 GeV/c per nucleon are presented. It is shown that the correlation of the yield of mirror 3H (3He) nuclei with the production of π + (π ?) mesons is due to the charge-exchange process involving an oxygen-nucleus proton (neutron) knocked out predominantly from an alpha-particle cluster. 相似文献

The review of the recent results on spin effects in few nucleon systems obtained at LHEP-JINR are presented. The data on the deuteron analyzing powers in different reactions in the wide energy range demonstrate the sensitivity to the spin structure of the light nuclei. The future plans on the studies with polarized deuterons from new polarized ion source at Nuclotron will be reported. 相似文献

New experimental data on the dependences of the mean multiplicities and kinematical characteristics of deuterons produced
in 16Op collisions at a momentum of 3.25 GeV/c per nucleon on the degree of excitation of the fragmenting nucleus are presented. These experimental data are compared with
the predictions of the cascade-fragmentation-evaporation model. 相似文献
