M. Ho et al., MEASURES OF DISTANCE FOR ATOMIC CHARGE AND MOMENTUM DENSITIES AND THEIR RELATIONSHIP TO PHYSICAL-PROPERTIES, International journal of quantum chemistry, 53(6), 1995, pp. 627-633
Atomic charge and momentum densities of 91 atoms (He-U) are classified
in terms of their L1, L2, and entropic measures of distance from the
densities of the preceding atoms. The relationship between these dista
nces and the first ionization energies is also considered. (C) 1995 Jo
