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

一些重元素的精确计算， 考虑碰撞激发的电离的各个阶段， 辐射跃迁，光电离和复合将是 使用R矩阵方法进行。 重点将主要是 铁周期元素，以解决明显的 在天文学物体中镍相对于铁过量。 迄今为止没有考虑的相对论效应将被 在计算中加入了原子数据库 建造和一些天体物理模型进行。 密切 与Opacity项目合作。 的 计算将在俄亥俄州的Cray YMP上进行， 没有NSF的费用。

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.
