Unfolding the prompt gamma ray spectra measured by a Lanthanum Bromide detector using GRAVEL method

In recent years, there has been renewed interest in the accurate measurement of prompt fission gamma ray spectrum (PFGS) of actinides primarily due to the requirement of precise data for Gen-IV reactor systems. It is also noted that prompt fission gamma-rays reveal detailed information about the dynamics of the fission process, particularly, energy partitioning in fission. With advanced scintillation detectors based on Lanthanum and Cerium Halides, accurate determination of PFGS characteristics is now possible. This paper describes the application of GRAVEL method for unfolding the prompt fission gamma energy spectra in the spontaneous fission of ²⁵²Cf measured using a Lanthanum Bromide detector
