A MEASUREMENT ON ENERGY-POOLING COLLISION CROSS SECTION IN Mg
-
Abstract
The energy-pooling collision cross section for the transfer from 3s3p1P to 3s4s3S of Mg has been determined by measuring the relative intensity of the fluorescence at 5184 Å and 2852 Å. The average cross section is (3.1±40%) x10-15cm2. By considering the influence of radiation trapping and other uncertain effects, the absolute uncertainty of our measurement is within one order of magnitude.
