Abstract: Using the liquid drop model and the jellium model, we calculate fission barrier heights as a function of charge and mass asymmetry for a family of shapes consisting of two spheres connected by a quadratic surface. We find the fissibility for which a mass asymmetric splitting gives place to the symmetric one (Bussinaro-Gallone point) and evaluate the size of results for the critical sizes agree very well with experiment.
