The fitting model adopted for the analysis of alpha spectra from silicon detectors is the convolution of a Gaussian and a weighted sum of exponentials. Details of this analytical function were published previously. This model was used in measurements of the alpha emission probabilities (P[alpha]) of various actinides including [sup 237]Np, [sup 236]Pu, [sup 239]Pu, and [sup 243]Am. It also enables the analysis of spectra from mixed actinides, e.g., [sup 239/240]Pu and [sup 238]Pu/[sup 241]Am. In the case of the [sup 237]Np, the accuracy of the P[alpha] data for the major lines was improved by more than one order of magnitude.
