Abstract
Spatial distributions of atomic vapors of alkaline earth elements around a tantalumfilament atomizer were studied in conjunction with the dissociation energy of diatomic oxide molecules. The spatial distributions of atoms in Ar atmosphere were narrower in the order which was coincident with the order of dissociation energy of oxide in magnitude. The presence of hydrogen (ca. 1%) in the purge gas expanded significantly the narrow distributions.
