# This example consists of several atomic energy calculations:

# - Formation energy of the H-atom w.r.t. spherical atom
# - Formation energy of the H-atom w.r.t. spherical atom
# - Spin polarization energy of the H-atom w.r.t. spherical atom
# - Spin polarization (relativistic) energy of the H-atom w.r.t. spherical atom
# - Spin polarization energy of the H-atom w.r.t. spin unrestricted atom
# - Spin polarization (relativistic) energy of the H-atom w.r.t. spin
#   unrestricted atom
