C  ****************** FORTRAN77 SUBROUTINE: C6TBFM *********************
C
C  PURPOSE:  FILLS TABLES OF  MAGNETIC FIELD DEPENDENT MIXING RATE
C            COEFFICIENTS BETWEEN NEARLY DEGENERATE LEVELS FOR
C            HYDROGEN-LIKE, LITHIUM-LIKE AND SODIUM-LIKE IONS.
C
C            RATES ARE CALCULATED FOR THE SEPARATE NLJ->NL+1J',
C            NLJ->NLJ' AND NLJ->NL-1J' TRANSITIONS.

C
C NOTES:
C       1) THE J->J' TRANSITION INDEX IS AS FOLLOWS:
C              1 : J=L+0.5 -> J'=L'+0.5
C              2 : J=L+0.5 -> J'=L'-0.5
C              3 : J=L-0.5 -> J'=L'+0.5
C              4 : J=L-0.5 -> J'=L'-0.5
C
C       2) BEFORE CALLING C6TBQM THE LIFETIME TABLE MUST BE FILLED
C          WITH A CALL TO C6TBLF.
