摘要：

An expression for an approximation of the deconvolution of the Voigt integral is presented. The results derived from this approach are discussed. It is found that the expressions proposed here give better results in the range of 2 < alpha < infinity than those approximations published previously. The FWHMs of the Lorentzian GAMMA-L and Gaussian GAMMA-G profiles are estimated whenever the Gaussian contribution to the Voigt profile be small, i.e. alpha > 2.
