<p>
An atomic shell pair couple is the cartesian product between two sets of functions, one
set over electron one and one set over electron two. Both sets are atomic shell
pairs.
</p>
<p>
These are usually called <i>shell quartets</i> in the literature, but we prefer to use
<i>pair</i> for two functions with the same electron, and <i>couple</i> for two functions
acting on different electrons, since they will be coupled by a two-electron operator.

* Atomic shell pair couple
:PROPERTIES:
:header-args: :noweb yes :comments both
:END:
An atomic shell pair couple is the cartesian product between two sets of functions, one
set over electron one and one set over electron two. Both sets are atomic shell
pairs.
These are usually called /shell quartets/ in the literature, but we prefer to use
/pair/ for two functions with the same electron, and /couple/ for two functions
acting on different electrons, since they will be coupled by a two-electron operator.

(** Data structure describing a couple of atomic shells pairs.
An atomic shell pair couple is the cartesian product between two sets of functions, one
set over electron one and one set over electron two. Both sets are atomic shell
pairs.
These are usually called {e shell quartets} in the literature, but we prefer to use
{e pair} for two functions with the same electron, and {e couple} for two functions
acting on different electrons, since they will be coupled by a two-electron operator.
