ryd-numerov 0.5.5

A Python package for calculating Rydberg wavefunctions.

Rydberg Numerov

The Rydberg Numerov software calculates properties of Rydberg states. We especially focus on the calculation of the radial wavefunction of Rydberg states via the Numerov method. The software can be installed via pip (requires Python >= 3.9):

pip install ryd-numerov

To install the latest development version from github, use:

pip install git+https://github.com/pairinteraction/ryd-numerov
