Pre-scission neutron multiplicity following the /sup 16/O+/sup 142/Nd reaction

Journal Article · · Phys. Rev. C; (United States)
Fission fragment-neutron angular correlations have been measured for the reaction 178 MeV /sup 16/O+/sup 142/Nd, allowing determination of the pre-scission and total neutron multiplicities. The total multiplicity agrees well with expectations based on energy balance, unlike the value obtained in a previous measurement. The pre-scission multiplicity of 4.2 +- 0.3 is much higher than the previous value (2.7 +- 0.4), leading to a considerably longer fission time scale and higher nuclear viscosity.
