.. _module_nuclei:
.. program:: nuclei
.. default-role:: option
======
nuclei
======
This module contains data relative to the nuclei (coordinates, charge,
nuclear repulsion energy, etc).
The coordinates are expressed in atomic units.
EZFIO parameters
----------------
.. option:: nucl_num
Number of nuclei
.. option:: nucl_label
Nuclear labels
.. option:: nucl_charge
Nuclear charges
.. option:: nucl_coord
Nuclear coordinates in the format (:, {x,y,z})
.. option:: disk_access_nuclear_repulsion
Read/Write Nuclear Repulsion from/to disk [ Write | Read | None ]
Default: None
.. option:: nuclear_repulsion
Nuclear repulsion (Computed automaticaly or Read in the |EZFIO|)
