Some special features of the momentum spectrum of protons produced in <Superscript>16</Superscript>O<Emphasis Type="Italic">p</Emphasis> collisions at a momentum of 3.25 GeV/<Emphasis Type="Italic">c</Emphasis> per nucleon

The momentum features of protons originating from ¹⁶Op collisions at a momentum of 3.25 GeV/c per nucleon are analyzed. It is shown that the degree of excitation of the fragmenting nucleus affects predominantly the shape of the momentum spectrum of protons emitted into the backward hemisphere in the rest frame of the projectile nucleus and partly the shape of the spectra of protons emitted into the forward hemisphere and formed via the mechanisms of Fermi breakup and evaporation.     

Production of mirror nuclei <Superscript>7</Superscript>Li and <Superscript>7</Superscript>Be in <Superscript>16</Superscript>O<Emphasis Type="Italic">p</Emphasis> interactions at a momentum of 3.25 GeV/<Emphasis Type="Italic">c</Emphasis> per nucleon

Results of a comparative analysis of processes leading to the production of mirror nuclei ⁷Li and ⁷Be in ¹⁶Op collisions at a momentum of 3.25 GeV/c per nucleon are presented. A comparison of associated multiplicities of accompanying particles is performed. The first results on the mean multiplicity of neutrons appearing as fragments are described.     

Dependence of the divacancy concentration on the germanium content in Si<Subscript>1 − <Emphasis Type="Italic">x</Emphasis></Subscript>Ge<Subscript><Emphasis Type="Italic">x</Emphasis></Subscript> alloys under irradiation by fast and slow neutrons

The concentration of divacancies formed in Si_{1 ? x} Ge _x solid solutions under irradiation by fast and slow neutrons is investigated as a function of the germanium content. It is demonstrated that the role of annihilation of primary radiation-induced defects on germanium atoms in the compounds under investigation decreases upon irradiation by fast and slow neutrons.     

Formation of multinucleon systems and nuclei with mass numbers of 6 and 7 in <Superscript>16</Superscript>O<Emphasis Type="Italic">p</Emphasis> interactions at a momentum of 3.25 GeV/<Emphasis Type="Italic">c</Emphasis> per nucleon

The results of a comparative analysis of the multiplicities of singly and doubly charged accompanying particles in the channels involving the production of six- and seven-nucleon systems in ¹⁶Op collisions at a momentum of 3.25 GeV/c per nucleon are reported. Cross sections for the yield of multinucleon systems and mean multiplicities of accompanying particles are found. The experimental data are compared with the predictions of the cascade—fragmentation—evaporation model.     

Rapidity and azimuthal correlations in π − p and π −C collisions at 40 GeV/c

New results are presented that were obtained from an analysis of experimental data on rapidity and azimuthal correlations in π ^? p and π ^?C collisions at 40 GeV/c. Some nonstandard methods for seeking correlations are developed. Dynamical correlations associated with fluctuations of the number of intranuclear collisions at a given multiplicity are discovered in π ^?C collisions. It is shown that the Lund model cannot describe the experimental data being discussed.

Production of $ \Delta$(1232) -resonances on oxygen nuclei in 16O + p collisions at a momentum of 3.25 GeV/c per nucleon

The production of D⁺⁺ \Delta^{{++}}_{} and D⁰ \Delta^{0}_{} resonances on oxygen nuclei in ¹⁶O + p interactions at 3.25A GeV/c was investigated with 4p \pi acceptance. The masses and widths of the resonances were obtained from an analysis of the experimental and background invariant-mass distributions of pp^± \pi^{{\pm}}_{} pairs. The fractions of charged pions coming from D⁺⁺ \Delta^{{++}}_{} and D⁰ \Delta^{0}_{} decay were estimated. The momentum, kinetic energy, and emission angle distributions of D⁺⁺ \Delta^{{++}}_{} and D⁰ \Delta^{0}_{} resonances were reconstructed in the oxygen nucleus rest frame. The slope parameters, T₀ , of the reconstructed spectra of invariant cross-sections of D⁺⁺ \Delta^{{++}}_{} and D⁰ \Delta^{0}_{} resonances, produced on oxygen nuclei in ¹⁶O + p interactions at 3.25A GeV/c , were determined.
