N2 - A novel technique is presented for measurements of neutron and gamma-ray time-dependent cross-correlation (cc) functions from alpha-n and spontaneous-fission sources. A system based on a fast multi-channel waveform digitizer, organic liquid scintillation detectors, and analysis algorithms was developed at the University of Michigan by the Detection for Nuclear Nonproliferation Group. Measured total and partial cc functions are presented for Cf-252 and Pu-Be sources. The results indicate that an alpha-n source can be distinguished from a spontaneous-fission source by (visual) inspection of the shape of measured cc functions.
