Results from the nuclear recoil calibration of the XENON100 dark matter
detector installed underground at the Laboratori Nazionali del Gran Sasso
(LNGS), Italy are presented. Data from measurements with an external 241AmBe
neutron source are compared with a detailed Monte Carlo simulation which is
used to extract the energy dependent charge-yield Qy and relative scintillation
efficiency Leff. A very good level of absolute spectral matching is achieved in
both observable signal channels - scintillation S1 and ionization S2 - along
with agreement in the 2-dimensional particle discrimination space. The results
confirm the validity of the derived signal acceptance in earlier reported dark
matter searches of the XENON100 experiment.
