Radial Matrix Elements

For the program pointc alternatively, the radial matrix elements can be given:

#---------------------------------------------------------
# Radial Matrix Elements (e.g. Abragam Bleaney 1971 p 399)
#---------------------------------------------------------
#<r^2> in units of a0^2 a0=0.5292 Angstroem
R2=1.114
#<r^4> in units of a0^4 a0=0.5292 Angstroem
R4=2.91
#<r^6> in units of a0^6 a0=0.5292 Angstroem
R6=15.03
