On production of charmed nuclei in charm exchange (D, π) reactions at thecτ-factory

The yield of charmed nuclei with the\(\Lambda _C^ + \)-baryon is estimated for a thin (100 μm) target placed at a distanceR=(30÷100) μm from thecτ-factory beam intersection point. The requirements to thecτ-factory beams for carring out the experiment on, the search for charmed nuclei are formulated: the luminosityL≥5·1033cm−2s−1, the beam cross dimensions σ≤3μm at least in one plane.
