Experimental spectra analysis in THM with the help of simulation based on Geant4 framework

摘要

The Coulomb barrier and electron screening cause difficulties in directlymeasuring nuclear reaction cross sections of charged particles in astrophysicalenergies. The Trojan-horse method has been introduced to solve the difficultiesas a powerful indirect tool. In order to understand experimental spectrabetter, Geant4 is employed to simulate the method for the first time. Validityand reliability of the simulation are examined by comparing the experimentaldata with simulated results. The Geant4 simulation can give useful informationto understand the experimental spectra better in data analysis and isbeneficial to the design for future related experiments.
