On the adequacy between the laser diffraction diameter distribution and the 3-parameter Generalized-Gamma function

► 3-Parameter Generalized-Gamma function well represents laser diffraction distribution. ► The fractal dimension in the small drop population is established and well reproduced. ► The mean-diameter series is also well reproduced. ► This work shows that parameter instability reported in the literature can be avoided. ► Interpretation of the mathematical parameters is suggested.
