A new Fortran program for the 9-j angular momentum coefficient. Program title: NINEJ: Nature of problem: The program calculates the 9-j coefficient (also called as the ls-jj transformation coefficient), using the single sum formula or the triple- sum formula due to Jucys and Bandzaitis. This coefficient arises in the recoupling of four angular momenta, which can be coupled either using the Russell-Saunders scheme or the jj-coupling scheme. It is of fundamental importance in the evaluation of matrix elements which occur in nuclear, atomic and molecular physics calculations.
