We show that the statistics of charge transfers can be interpreted in terms of single electrons and spin-singlet pairs coming from the source. If the source contains transport channels of high transparency, a significant fraction of electrons comes in spin-singlet pairs.4 pages, 1 figureMesoscale and Nanoscale PhysicsQuantum Physicstext
