Scaling of state multipoles; a critical test of the scaling relations

Abstract

Scaling laws for rotational energy transfer may be written for transfer of polarisation as well as for transfer of population. Here we derive an expression, based on the sudden scaling relations, for the transfer of stare multipoles following energy transfer. Some current fitting laws are tested using Li 2 */He, Li 2 */Ar circular polarisation data. We find that polarisation ratios provide a more stringent test of scaling and fitting relations than do unpolarised intensities and that the power gap law yields the best fit for both sets of data examined here.
