Theoretical study for the global parameters covering the d-d thermonuclear fusion reaction

Adjusting the calculation related with the parameters that control the physical behaviors for the fusion phenomena occurs in the controlled thermonuclear fusion reactions needs to fix a very suitable and compatible data or formula for the common factor such as cross sections and/or astrophysical S-factor that play important rules for arriving in acceptable theoretical results for other parameters that give a good agreement with corresponding experimental data.
