# 3.5.7. horton.grid.poisson – Becke-style numerical Poisson solver¶

horton.grid.poisson.solve_poisson_becke(*args, **kwargs)

Compute the electrostatic potential of a density expanded in real spherical harmonics

Arguments:

density_decomposition
A list of cubic splines returned by the method AtomicGrid.get_spherical_decomposition.

The returned list of splines is a spherical decomposition of the hartree potential (felt by a particle with the same charge unit as the density).
