2. Fo and T can now be evaluated nmerically. For mercury the four transitions t the ground state 61s0- 61P1(1850 ), 6 s0- 63P2 !2210 A>61s0- 63P1(2517 AJ, and 61S0- 6 P1 (2656 ) must be considered. The first of these is a transition between singlet states and the latter three are intercombination lines. Table B-1 summarizes the relevant quantities for these lines. The computedF0
