Developed spectral analysis software in C++ Builder GFS2016

Applied method to 240Pu+48Ca fusion reaction

Abstract

Method of active correlations is a key one to suppress radically beam associated backgrounds in heavy ion induced complete fusion nuclear reactions. This property is enhanced significantly when applying DSSSD detector instead of position sensitive resistive strip detector. Example of application in the 240Pu+48Ca->114+3n reaction is presented. An edge effect between neighbor strips is considered too. The value of the mentioned effect is measured as 15.9 percents for ER-alpha correlation chains. C++ Builder GFS2016 program package for spectral analysis is presented. Calibration parameters (totally 352) were obtained from natYb+48Ca nuclear reaction. New ultra intense FLNR DC280 cyclotron that is expected to be put into operation in the nearest future is also discussed from the viewpoint of the described method developments.
