Development Of A Lorentzian-Function Approximation Utilizing In The Charged-Particle-Induced Nonresonant Reaction Rate

A development has been made for the charged-particle-induced nonresonant reaction-rate equations. The forms of reaction-rate equations for nonresonant and resonant reactions have been united in a frame of Lorentzian-Function Approximation (LFA) mathematically. In the frame of LFA, the nonresonant reaction taken place within the Gamow window can be considered, in form, as a "resonance" reaction with a full width at half maximum (FWHM, Gamma(nr)) equal to the 1/e width (Delta) in a well-known Gaussian-Function Approximation (GFA).
