Abstract

The emerging experimental program for photofission research at ELI-NP is briefly summarized. GEANT4 Monte Carlo simulations, providing estimates of the collimated beam profile of the ELI-NP gamma beam: beam energy bandwidth and beam spot dimensions, the required target dimensions, and fission fragment emission rates, their mass and energy distributions, have been reported, which ensure the feasibility of high-resolution studies of the multiple-humped fission barrier. A spectrometer consisting of four ionization chambers coupled to Si strip detectors, called ELI-BIC, is being developed for these measurements, and is briefly discussed.
