    Influence of some technological parameters on the contrast of laser marking on the fly

    For the purpose of optimizing on-the-fly laser marking of tool steel products there have been analyzed experimental results related to the dependences of contrast on power density and speed. Research has been ...

    Spin physics with antiprotons

    New possibilities arising from the availability at GSI of antiproton beams, possibly polarised, are discussed. The investigation of the nucleon structure can be boosted by accessing in Drell-Yan processes expe...

    Multiplicity, momentum and angular distributions of protons from the interactions ofp, d, α andC with carbon at 4.2 GeV/c/nucleon momentum

    Average multiplicity of protons fromp, d, α andC interactions with carbon at 4.2 GeV/c/ N is shown to increase with the mass number of incident nucleus. ThisA dependence is stronger for fast protons than for the ...

    Interference of secondary pions and time-space characteristics of their emission volume in π− p interactions at 40 GeV/c

    The interference of positive and negative pions produced in π− p interactions at 40 GeV/c is studied. It is shown that negative pions are emitted from larger distance than positive ones. The influence of resonan...
