Emissivity: A Program for Atomic Emissivity Calculations

Relativistic calculations of atomic structure

This paper is intended to give a review on relativistic atomic structure calculations [1] with emphasis on the Multiconfigurational-Dirac-Foek method, Dr Crossley has summarized in his preeeeding paper most of the non-relativistic methods whieh lead to good binding energies and transition probabilities. Both quantities are espeeially important in astrophysies and plasma physies. Sinee relativis...

Atomic spectral methods for molecular electronic structure calculations.

Theoretical methods are reported for ab initio calculations of the adiabatic (Born-Oppenheimer) electronic wave functions and potential energy surfaces of molecules and other atomic aggregates. An outer product of complete sets of atomic eigenstates familiar from perturbation-theoretical treatments of long-range interactions is employed as a representational basis without prior enforcement of a...

All-Order Methods for Relativistic Atomic Structure Calculations

All-order extensions of relativistic atomic many-body perturbation theory are described and applied to predict properties of heavy atoms. Limitations of relativistic many-body perturbation theory are first discussed and the need for all-order calculations is established. An account is then given of relativistic all-order calculations based on a linearized version of the coupled-cluster expansio...

Developing a mobile application for usual calculations of radiotherapy physics

Introduction: Successful radiotherapy requires the precise application of a radiation dose to cancerous tissue, which can be achieved by the design of proper treatment methods by radiotherapy physicists. Tasks performed by radiotherapy physicists include verifying the accuracy of dose calculations, correct treatment planning and the proper functioning of accelerators. They are...
