Procedures for integration over the spin variables are not the concern of the present work, and we proceed under the assumption that the spin integrations of the energy expectation value have been completed. We are thus left with the evaluation of t

I, J denote nuclei; i, j denote electrons and .denotes the distance between nucleus I and electron i. In addition to equation (1), the wavefunction . must obey the Pauli Principle.Where. permutes the coord

Communications and Control Engineerings gaseous material located between the stars: the interstellar matter (ISM). The principal constituents of interstellar matter are gas and fine dust particles. The qas consists mainly of hydrogen and helium, with an approximate ratio by mass of H: He: (all heavier elements) = 70:28:2. Dust accounts
