Calculation of negative ions of B, C, N, O and F using noninteger n Slater type orbitals
No full textCombined Hartree-Fock-Roothaan calculations have been performed using noninteger n Slater type orbitals for the ground states of the lowest electron configurations 1s(2)2s(2)2p(n) (2 <= n <= 6) for negative ions of B, C, N, O and F. These results are compared with the corresponding results obtained from the use of integer n Slater type orbitals. All of the nonlinear parameters are fully optimized. The results of calculation of coupling-projection coefficients, orbital and total energies and virial ratios are presented. It is shown that the noninteger n Slater type orbitals, in general, improve the orbital energies

O. A. C. Review Volume XX Issue 1, October 1907
No full textThis issue starts the new school year with an overview of Ontario Agricultural Societies and profiles of two agricultural colleges: Macdonald College in Quebec and Manitoba Agricultural College. Agricultural articles review the Ontario potato industry and personal perspective on the 1906 Winter Fair in Guelph. The Horticultural column started a series of articles on experimental horticulture in Canada. Campus articles pertain to a student's experience working in a mine, the freshman initiation and athletics and Y. M. C. A. reports. Alumni news is available in the Our Old Boys column and this issue profiles each member of the O. A.
