In a four-day all-Europe conference on atomic structure and spectroscopy special attention was given to isotope shifts, level crossing hyperfine spectroscopy, in addition to conventional analysis of atomic energy levels and spectra. There were numerous applications of lasers to spectroscopy and one paper on beam-foil excitation. (Author)
A program prepared for the IBM 7090 to solve the general form of the Hartree-Fock equations is described. The program is written in FORTRAN II except for three subroutines which are written in the FAP language. It is divided into four parts which contain: I. Basic theory and method of numerical solution; II. User's guide to the program; III. Subroutine Specifications; IV. Flow diagrams and ...
The observed energy levels for Silicon + 3 have been fit by adding a polarisation term to the potential of the Hartree-Fock equation in a manner first used by Douglas. The resulting wave functions were used to calculate transition integrals for the allowed transitions and compared with the results using no polarisation term; the differences were of the order of a few percent. Results of calculations done on Silicon + ...
