Previous: The subroutine SLS
The routine determines the value of the reduced matrix element:
![\begin{displaymath}
( l QLS \vert\vert\vert [ a^{(qls)} \times a^{(qls)} ]^{(k_{1}k_{2}k_{3})} \vert\vert\vert l Q'L'S' ).
\end{displaymath}](img377.png) |
(35) |
The routine uses the tables of reduced matrix elements of the tensor
operator
for s-, p - and d - subshells (see Špakauskas et al [13]),
and for the f - shell the expression (34) from paper P1 [3] is used.
The subroutine does not calculate the simple case
of
,
because then the operator is just
(expression (15.54) in Rudzikas [14]).
The subroutine has the formal arguments:
- K1 is the rank
.
- K2 is the rank
.
- K3 is the rank
.
- L is the orbital quantum number l.
- J1 is the state number of the bra function (see Tables 1, 2).
- J2 is the state number of the ket function.
- W is the value of the reduced matrix element
(35) which is returned by
the subroutine.
