Determination of Total Absorption of Na3S → nP Transitions for 5 ≦ n ≦ 28
Keyword(s):
Total absorption measurements of Na3S → nP transitions up to a main quantum number n = 28 have been performed at Na number densities in the range ≈ 1016 - 1017 cm-3 and temperatures ≈ 700-800 K. A heat pipe oven has been applied as an absorption tube in a single beam optical arrangement; experiment and data acquisition have been controlled by a computer. The results are compared with calculations using special assumptions with respect to line broadening mechanisms. The effect of binary and three-body collisions on total absorption is studied in detail. Within the pressure and main quantum number range investigated here a transition between the two types of interaction was demonstrated.
