The absolute threshold photodetachment cross-section of Al-
Creators
Description
The total absolute photodetachment cross-section of the aluminum anion, Al-, is calculated in the threshold spectral region for photons of wave numbers 3400 - 3650cm-1 using the zero-core contribution (ZCC) model. A computer least-squares curve fit is used to test the validity of the Wigner threshold law and the deviation from recent experimental measurements of the relative photodetachment cross-section. It is found that the best agreements is achieved with a smaller core radius rο=1.60 Angstrom rather than the value of 1.82 Angstrom used earlier. (authors). 22 refs., 5 figs., 1 tab
