ao_basis
========

This module describes the atomic orbitals basis set.

An |AO| :math:`\chi` centered on nucleus A is represented as:

.. math::

   \chi_i({\bf r}) = (x-X_A)^a (y-Y_A)^b (z-Z_A)^c \sum_k c_{ki} e^{-\gamma_{ki} |{\bf r} - {\bf R}_A|^2}


The |AO| coefficients are normalized as:

.. math::

  {\tilde c}_{ki} = \frac{c_{ki}}{ \int \left( (x-X_A)^a (y-Y_A)^b (z-Z_A)^c  e^{-\gamma_{ki} |{\bf r} - {\bf R}_A|^2} \right)^2 dr}

Warning: `ao_coef` contains the |AO| coefficients given in input. These do not
include the normalization constant of the |AO|. The `ao_coef_normalized` provider includes
this normalization factor.

The |AOs| are also sorted by increasing exponent to accelerate the calculation of
the two electron integrals.



 
 
 
EZFIO parameters 
---------------- 
 
.. option:: ao_basis
 
    Name of the |AO| basis set
 
 
.. option:: ao_num
 
    Number of |AOs|
 
 
.. option:: ao_prim_num
 
    Number of primitives per |AO|
 
 
.. option:: ao_prim_num_max
 
    Maximum number of primitives
 
    Default: =maxval(ao_basis.ao_prim_num)
 
.. option:: ao_nucl
 
    Index of the nucleus on which the |AO| is centered
 
 
.. option:: ao_power
 
    Powers of x, y and z for each |AO|
 
 
.. option:: ao_coef
 
    Primitive coefficients, read from input. Those should not be used directly, as the MOs are expressed on the basis of **normalized** AOs.
 
 
.. option:: ao_expo
 
    Exponents for each primitive of each |AO|
 
 
.. option:: ao_md5
 
    MD5 key, specific of the |AO| basis
 
 
.. option:: ao_cartesian
 
    If |true|, use |AOs| in Cartesian coordinates (6d,10f,...)
 
    Default: false
