Fortran Implementation for Nuclide Liquid Drop Model Calculations With Numerical Techniques

This research proposes a numerical variation method developed to find the best parameters of the nuclide liquid drop model in calculating its mass. This method was developed because there was no systematic method for finding empirical model parameters in calculating the nuclide mass or binding energy. The modelling used in this study uses the Fortran programming language or formula translation. The results obtained provide a very significant improvement in the model for calculating the mass of stable nuclides. The closeness of the empirical model calculation results to the experimental results shows the model's validity. The delta deviation results from the proposed numerical method give the smallest value compared to existing methods at 111. Meanwhile, the error rate in the proposed method is 0.00088% or 8.84 x 10-6.
