An overview of the recent results on fission dynamics from the NAND facility.

This paper summarizes the results of some of the recent fusion-fission experiments carried out at the National Array of Neutron Detectors (NAND) Phase-01 installed at the Pelletron + LINAC accelerator facility of Inter-University Accelerator Centre (IUAC), New Delhi. Pre-scission neutron multiplicity excitation functions are measured for the Fr, Rn and Po compound nuclei populated through the fusion of the F+Pt, O+Pt and C+Pt systems, respectively. Pre-scission neutron yields from these reactions are compared with the extensive statistical model calculations to look for the effects due to the compound nucleus shell closure, N/ Z ratio of the compound nucleus, magnitude of the saddle-point shell corerction and fission time-scale.
