The XENON100 experiment has completed a dark matter search with 100.9 live days of data, taken from January to June 2010. Events with energies between 8.4 and 44.6 keVnr in a fiducial volume containing 48 kg of liquid xenon have been analyzed. A total of three events have been found in the predefined signal region, compatible with the background prediction of (1.8±0.6) events. Based on this analysis we present limits on the WIMP-nucleon cross section for inelastic dark matter. With the present
