# HBrowse: a GRACE tool for browsing R-matrix H-files

## Description

Abstract An H-file is used to convey information from the inner-region to the outer-region in R-matrix computations. HBrowse is a workstation tool for displaying a graphical abstraction of a local or remote R-matrix H-file. While it is published as a stand-alone tool for post-processing the output from R-matrix inner-region computations it also forms part of the Graphical R-matrix Atomic Collision Environment (GRACE). HBrowse is written in C and OSF/Motif for the UNIX operating system. Title of program: HBrowse 2.00 Catalogue Id: ADMM_v1_0 Nature of problem For many years the R-matrix method and its associated computer programs [1-4] have been widely used in the study of a diverse range of electron-atom and electron-ion collision processes. Normally, R-matrix computations involve the division of configuration space into two regions: the inner-region and the outer-region. On completion of an inner-region computation, intermediate data describing the physics of the computation is numerically encoded in Fortran data structures, packaged into Fortran f ...
