The README File

File szabo.f contains source for a simple HF calculation (STO-3G) with only s orbitals for molecule HeH+ . The source is listed in the book 'Modern Quantum Chemistry', APPENDIX B: TWO-ELECTRON SELF-CONSISTENT-FIELD PROGRAM OF MODERN QUANTUM CHEMISTRY by Attila Szabo and Neil S. Ostlund. This old-fashioned fortran77 program compiles smoothly with a gfortran compiler, even if some warnings are displayed. For the underlying theory, please read the book... I think that this program could be useful for students and for all the readers that do not want to type in the program (and debug it).
