New additions
At present the HibridonTM package can be installed on the following machines:
IBM RS/6000 workstations running under AIX 3.2.5, 4.1.3, 4.1.4, 4.2, 4.3
HP 9000 series workstations running under HPUX 9.03, 10.01, 10.2, 11.0
DEC Alpha workstations running under OSF 41.64
SGI workstations running under IRIX 5.2 and 6.5
Sun workstations running under SunOS 5.5.1 and 5.7
The HP (10.2 and 11.0) and IBM (4.3) versions are actively maintained;those on the other platforms
are maintained on a less regular basis
You can obtain a copy of the HibridonTM package as
a compressed tar archive in binary format (1.6 MB)
a UUencoded compressed tar archive in ascii format (2.3 MB)
This hypertext help facility will guide you in the installation and application of HibridonTM. To ensure the proper display of special characters, your ASCII encoding should be set to ISO 8859-1 (Latin-1) Characters.

Installation instructions for the HibridonTM package are
available here
Installation also creates your own copy of these hypertext help files.
Calculations on any particular collision system involve linking several system specific subroutines which define the interaction potential energy surface(s) together with a large number of general routines, which have be compiled previously.
Execution of the HibridonTM package is controlled by the Hibridon driver.
- For a description of the commands to the driver,
- The scattering calculation is controlled by
- system independent parameters
- system dependent parameters
- logical flags
- input and output files, and job names
- At present HibridonTM can treat a number of different types
of collision sytems. This is made possible
by the presence of multiple system specific subroutines:
- BASIS subroutines which define the Hamiltonian matrix
- SYSDAT subroutines which control the input of system specific data
- System specific POT subroutines which determine
the distance dependence of the potential matrix
V(R). Go
for a list of the POT subroutines which
have been furnished with the HibridonTM package.
A number of examples have been prepared to help you learn how to use the HibridonTM package. These are particularly instructive once you have had an initial exposure to this help library.
The HibridonTM package was written by M. H. Alexander, D. E. Manolopoulos, H.-J. Werner, and B. Follmeg, with contributions by P. F. Vohralik, D. Lemoine, G. Corey, R. Gordon, B. Johnson, T. Orlikowski, A. Berning, A. Degli-Esposti, C. Rist, P. Dagdigian, B. Pouilly, G. van der Sanden, M. Yang, F. de Weerd, and S. Gregurick. Support for its development was provided by grants (to MHA) from the U. S. National Science Foundation, the U. S. Army Research Office, the Office of Scientific Research of the U. S. Air Force, and (to HJW) from the German Fonds der Chemische Industrie. Copyright (c) 1987, 1991, 1993, 1996, 2003, University of Maryland at College Park. All rights reserved.
