Effect of nuclear transparency from the (p,2p) measurements on 6Li and 12C at 1 GeV

We studied the production of protons to the backward direction in (p,2p) reactions on 6Li and 12C, accompanied by a proton emitted into the forward hemisphere. The momenta of the final two protons were measured in a wide range with the two-arm time-of-flight spectrometer. For each event we reconstructed the mass of the intermediate off-shell particles. We have discovered a strong narrow dip in the mass spectra of intermediate mesons at the mass of the real pion.Comment: 24 pages,11 figure

ESTIMATION ОF THE ЕFFЕСТ ОF FINITE-VOLUME MESH PARAMETERS ON THE SIMULATION OF THE WORKING PROCESS OF AXIAL TURBINES

The paper gives recommendations on the creation of numerical models of the working process in axial turbines. The recommendations are based on the comparison between the flow structure and the model parameters: the 3D-mesh parameters and turbulence models. The recommendations make it possible to improve the efficiency of gas-dynamic design and development of aviation uncooled turbines
