The Iron Project: Large-scale Atomic Calculations for Iron-Period Elements

本文将使用r -矩阵方法对考虑碰撞激发、辐射跃迁、光电离和复合的若干重元素在电离的不同阶段进行精确计算。重点将主要集中在铁周期元素上，以解决天文物体中相对于铁的明显过量的Ni。迄今为止未考虑的相对论效应将被纳入计算，建立一个原子数据库并进行一些天体物理建模。希望与不透明度项目密切合作。这些计算将在俄亥俄州立大学的克雷YMP上进行，国家科学基金会不需要支付任何费用。

Accurate calculations for a number of heavy elements in various stages of ionization considering collisional excitation, radiative transitions, photoionization and recombination will be performed using the R-matrix method. The focus will be primarily on the Iron period elements in order to resolve the apparent overabundance of Ni relative to Iron in astronomical objects. Relativistic effects heretofore not considered will be incorporated into the calculations, an atomic database constructed and some astrophysical modelling performed. Close collaboration with the Opacity project is intended. The calculations will be performed on the Cray YMP at Ohio State at no cost to the NSF.
