Abstract The package fhi98PP allows one to generate norm-conserving pseudopotentials adapted to density-functional theory total-energy calculations for a multitude of elements throughout the periodic table, including first-row and transition metal elements. The package also facilitates a first assessment of the pseudopotentials' transferability, either in semilocal or fully separable form, by means of simple tests carried out for the free atom. Various parameterizations of the local-density approximat... Title of program: fhi98PP Catalogue Id: ADKA_v1_0 Nature of problem The norm-conserving pseudopotential concept allows for efficient and accurate ab initio electronic structure calculations of poly-atomic systems. The key features of this approach are: (i) Only the valence states need to be calculated. The core states are considered as chemically inert, and removed within the frozen-core approximation. This exploits that many chemical and physical processes are governed by the valence states but only indirectly involve the core states. (ii) The valence electrons ...
