J. Cederkall et al., RELATIVE ENHANCEMENT OF WEAK 2-NEUTRON EXIT CHANNELS IN HEAVY-ION-INDUCED FUSION-EVAPORATION REACTIONS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 385(1), 1997, pp. 166-170
A method to enhance weak two-neutron exit channels in heavy-ion induce
d fusion-evaporation reactions is demonstrated with a data set from th
e NORDBALL detector array, True two-neutron events are enhanced in rel
ation to spurious events from cross-talk by a factor of 30. In the pro
cess the peak-to-background ratio in the coincident gamma-ray spectra
improves more than 3 times.
