The symmetry of the lattice is fully repeated in the terms EV , ( R , - r ; ) and E ' ( ea / rii ) Q ;, so that the Bloch theorem can be proved and the wave functions 73 3 Yi are always of the form Yi ( r ) = uk ( r ) exp [ i kór ] ...

When k is represented by a point of high symmetry , the corresponding one - electron wave function can be classified according to their symmetry with respect to the operations that leave k unchanged . For example suppose k lies as ...

It is possible that the ground states of different families cross , but H has no matrix elements between them because H ( t ) preserves the symmetry properties on which the classification into families is based .
