报告摘要

As physicists we all learned how to estimate the uncertainties in experimental measurements, and error bars are a standard part of published results. However traditionally the same has not been true on the theoretical side. A lack of uncertainty estimates limits the usefulness of the results in comparing with experiment (do they agree or not?) or in applications to other areas such as astrophysics or plasma modeling. The situation is now changing with advances in techniques for estimating uncertainties, and requirements for uncertainty estimates in published data . The talk will focus on sources of uncertainty in calculated atomic and molecular data involving high precision measurements and scattering cross sections. Following a recent review article , the talk will discuss model uncertainties due to approximations to the fundamental many-body quantum mechanical equations with the aim of providing guidelines to estimate uncertainties as a routine part of computations of data for structure and scattering.
