1. 1. Total Monte Carlo of the fission model in GEF and its influence on the nuclear evaporation in TALYS

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Karlsson Peter; [2023]
   Keywords : physics; nuclear physics; fission; neutron-induced; evaporation; Hauser-Feshbach; GEF; TALYS; Total Monte Carlo; TMC; fysik; kärnfysik; neutron-inducerad;

   Abstract : Features recently added to the nuclear reaction software TALYS allow the use of the GEF model as a fission fragment generator. GEF generates data for fission fragment yields, total excitation energy (TXE), total kinetic energy (TKE) and individual fragment excitation energies (E*) with their standard deviations through Monte Carlo simulations for TALYS.

3. 2. Benchmark of the fission channels in TALYS

   University essay from

   Author : Fredrik Nordström; [2021]
   Keywords : Fission; Prompt neutrons; Prompt gamma-rays; Nuclear reaction codes; TALYS; GEF;

   Abstract : In this project, different fission models in the nuclear reaction code TALYS have been compared to GEF version 2020/1.2. The data included in the comparison are mass yield distributions, average prompt neutron energies per fragment mass, and average multiplicities of both neutrons and γ-rays per fragment mass.

4. 3. Benchmarking fission rate simulations through comparison with neutron activation data

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Karlsson Peter; [2020]
   Keywords : Neutron activation; Gamma spectroscopy; Fission;

   Abstract : Metal foils were implemented in a measurement of neutron-induced fission at the IGISOL facility in 2016. These foils were activated by a neutron flux during the experiment and measured after the beam was turned off. The radioactive products from the neutron activation were identified in an analysis of γ-ray spectroscopy data. READ MORE

5. 4. Experimental studies at CERN-nTOF of the 230Th(n,f) reaction

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Felicia Lapinski; [2020]
   Keywords : fission; neutron induced fission; fission cross section; fission fragment angular distribution; thorium;

   Abstract : This work investigates the feasibility to perform an experiment at CERN n_TOF to study the fission cross section and fission fragment angular distribution (FFAD) of the 230Th(n,f) reaction. An analysis of fission fragment energy losses in the experimental target resulted in a choice of target thickness of 0. READ MORE

6. 5. Implementation and characterization of Silicon detectors for studies on neutron-induced nuclear reactions

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Leo Lehtilä; [2019]
   Keywords : Silicon detector; Silicon telescope; Ultra-thin silicon detector; Energy resolution; Radioactive source; Am-241; Cf-252; Fission Fragments; Alpha Particles;

   Abstract : Energy resolution characteristics of silicon surface barrier detector signals amplified by different preamplifiers and spectroscopic amplifiers have been studied. The characterization has been done using alpha particles from an 241Am source and spontaneous fission fragments from two Cf sources. READ MORE
