This is the home page and hypertext help facility for Hibridon
©
, a program package
to solve the
close-coupled equations which occur in the quantum
treatment of inelastic atomic and molecular collisions. Gas-phase
scattering,
photodissociation, collisions
of atoms and/or molecules with flat
surfaces, and
bound states
of weakly-bound complexes can be treated. Although this hypertext help contains some general
formal material,
we assume here that you have some background with the quantum theory of inelastic
scattering.

Installation instructions for the Hibridon
© 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 Hibridon
© package is controlled by the Hibridon driver.
- For a description of the commands to the driver,
- The scattering calculation is controlled by
- At present Hibridon© 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 Hibridon© package.
A number of
examples have been prepared to help you learn
how to use the Hibridon
© package. These are particularly instructive once you have
had an initial exposure to this help library.
The Hibridon©
package was written by M.

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

This version of Hibridon is dedicated to the memories of Sheldon Green
and Peter Andresen, whose untimely deaths
robbed us of two outstanding scientists, and dear friends, who both made long-lasting and invaluable contributions
to the field of inelastic molecular collisions. Ave atque vale.
