With,sensitive space-charge-limited diode ionization detector, Re studied 8
-10s sigma, 8-10d sigma (1)Sigma(g)(+), and 10-15d pi (1)Pi(g) Rydberg stat
es of Na-2 and obtained their molecular constants for the first time. It is
the first successful example of a diode ionization detector that is used i
n a pulsed OODR molecular spectroscopy experiment. (C) 1999 Academic Press.
