Below I attached LaTex file with some diagram.
I need to adjust the length (make longer) of the
arrow which slopes from node (1,3) (\Gamma the upper right corner)
to (2,2) ( {\ds \tilde \Gamma_k} ).
Of course when I put just  {\ds \tilde \Gamma} without the subscript k
the diagram is satisfied but I need \Gamma with subscript k.

Does anybody know how to achieve that?
I think I could create the diagram not using psmatrix and psnode
but It seems that using psmatrix and psnode should be the
easiest.
