pyIBM: A user-friendly Python package for IBM/IBFM-1 calculations

pyIBM is a user-friendly Python package for performing IBM/IBFM-1 calculations.

We present two separate packages:

1. pyIBM: A stand-alone package with all Clebsch-Gordan (CG) coefficients up to N=10 stored in a library. One can do calculations with user-defined Hamiltonian parameters, optimize the parameters by providing a list of energy levels, or study the sensitivity of the solution to the choice of parameters by performing a 2D contour plot.
2. create_basis: A supplementary code package coupled to an executive file of a Fortran code which generates CG coefficients. The package first tries to read from the CG library, if the CG coefficients are not found, it calls the Fortran CG code to generate the coefficients and updates the library.
