# define the unit cell parameters:
#   space_group                      - the space group number or Hermann or Hall symbol [string]
#   lattice_a, ...b, ...c            - the lattice spacings a,b,c [angstrom]
#   lattice_alpha, ...beta, ...gamma - the lattice angles alpha,beta,gamma [degree]
#   debye_temp                       - the Debye temperature [K]

# add atoms to the unit cell:
# notation is "atom_number = name b_coh sigma_inc sigma_abs_2200 molar_mass x y z"
#   name           - labels the current atom/isotope  [string]
#   b_coh          - the coherent scattering length [fm]
#   sigma_inc      - the incoherent scattering cross section [barns]
#   sigma_abs_2200 - the absorption cross sect. at 2200 m/s [barns]
#   molar_mass     - the Molar mass [g/mol]
#   x y z          - the Wyckoff postion of the atom inside the unit cell
#
# e.g.: add_atom = Fe 9.45 0.4 2.56 55.85 0.0 0.0 0.0
