first-order perturbation theoryrelativistic energy corrections/ A3130J Radiative and relativistic effects (atoms and molecules)First-order relativistic calculations give a relative error in the estimate of the total correction which increases like Z 2 from 0.26% for neon to 8% for xenon....
However, it is still possible — and economical — to use perturbation theory as a first approximation in studies of phase transitions.5 For this reason, this section pedagogically describes a recipe for the purely perturbative analysis of cosmological phase transitions. In particular, it describes ...

The heuristically based generalized perturbation theory (HGPT), to first and higher order, applied to the neutron field of a reactor system, is discussed in relation to the criticality reset procedure. This procedure is implicit within the GPT methodology, corresponding to the so called filtering ...

A molecular thermodynamic model for the calculation of ionic mean activity coefficients in electrolyte aqueous solution is developed by treating the ion - ion electrostatic interactions with mean spherical approximation (MSA) of all particles in the solution and other interactions with perturbation theory,...
