Is there diffraction dissociation of nuclear nucleons in nucleus-nucleus interactions
Abstract:A new algorithm of accounting of the diffraction dissociation of nucleons in nucleus-nucleus interactions is proposed. A good description of the BMN collaboration data on π+ meson production in Ar – nucleus interactions has been reached, though there are left some problems.

Towards understanding of K0s meson production in hadronic interactions
Abstract:It is shown that the recent data by the NA61/SHINE collaboration on K0s meson production in pp interactions at Plab= 31, 40, 80 and 158 GeV/c are well described by the Geant4 FTF model without any tuning of the model parameters.

Microscopic analysis of elastic scattering and transfer reaction in the 7Li+10B collision at energy 58 MeV
Abstract:Analysis of cross sections of the 7Li+10B elastic scattering and the transfer reaction 7Li+10B → 6Li+11B at the beam energy Elab = 58 MeV is carried out by using the microscopic optical potential and the DWBA approach. The results are discussed in comparison with experimental data obtained in 2023 at the U-400 cyclotron in FLNR JINR.

Target Dependence jf the Isotope Distributions in Heavy-Ion Reactions at Fermi Energies
Abstract:In this report the experimental ratio of cross-sections obtained in the reactions on heavy 181Ta and light 9Be targets in the collision with projectile 18O at 35 MeV per nucleon is compared with the predictions of transport-statistical approach BNV-SMM and several frequently used models. The difference in the model results is discussed.
