Absolute normalization for uncorrelated background with the event mixing technique

We present a method to determine the magnitude of the uncorrelated background distribution obtained with the event mixing technique, through the simultaneous observation of the projectile elastic scattering in different detectors, which correspond to random coincidences. The procedure is tested with α–dα–d angular correlation data from the Li6+Co59 reaction at Elab=29.6MeV. We also show that the method can be applied using the product of singles events, when singles measurements are available.
