摘要：

We report experiments using a silicon target exposed to a neutron source, giving both nuclear recoil events from neutron scattering and electron recoil events from photon scattering. We show that simultaneous measurement of ionization and thermal energy for each event allows the neutron and photon events to be separated. The degree of separation of the nuclear recoil events, and their absolute event rate, are consistent with theoretical expectation.
