The ESR spectrum and linewidth measurements of atomic iodinea)

摘要

The experimental spectrum from groundhyphen;state2P3/2atomic iodine is compared with a theoretical calculation using a besthyphen;fitgvalue equal to 1.333980plusmn;0.000006 and previously determined nuclear and electronic spin interaction constants. A rate coefficient for iodinehyphen;atom wall recombination (ggr;quest;10minus;3) is reported. Broadening coefficients and hyperfine interaction relaxation cross sections for the iodinehyphen;atom ground state with He, O2, and HI are determined from the line broadening of theMJ=3/2rarr;1/2 andMJ=1/2rarr;minus;1/2 transitions of I and compared with theory.
