Gamma-Ray Multiplicities and Fission Modes inP208b(O18,f)

Gamma-ray multiplicities and fission modes in (208)Pb((18)O,f).

Two components in the M(gamma)(M) distribution were established in detailed measurements of mean gamma-ray multiplicities from fission fragments of (226)Th. For the first time in the M(gamma)(M) dependencies we were able to distinguish two components associated with primary and the final (after the neutron evaporation) fission fragments, and show that at the scission point M(gamma) is extremely...

Measurement and Simulation of Neutron/Gamma-Ray Cross-Correlation Functions from Spontaneous Fission

We present an application of a digital pulse shape discrimination (PSD) technique for the novel measurement of cross-correlation functions from a spontaneous fission source. The measurement method allows for the collection of fast coincidences within a time window of the order of a few tens of nanoseconds. The use of PSD allows for the accurate acquisition of the coincidences in all particle co...
