Two methods of the luminosity determination for the experiment performed by
WASA collaboration to search for 4â0.03cmHe-Ρ bound state are
presented. During the measurement the technique of continous change of the beam
momentum in one accelerator cycle (called ramped beam) was applied. This
imposes the requirement to determine not only the total integrated luminosity,
but also its variation as a function of the beam momentum.Comment: Symposium on Applied Nuclear Physics and Innovative Technologies,
