6 ) where r ; is the distance of the sth ion from the reference ion and is always to
be taken as positive . We shall first compute the value of the Madelung constant
for an infinite line of ions of alternating sign , as shown in Fig . 2 . 2 . We pick a ...

validity of the ionic radius concept is a consequence of the very strong
dependence of the repulsive forces on interionic distance . The tailing - off of the
radial wave functions according to quantum mechanics tells us that no absolute ...
