( 19 ) this permits no motion of any atom , because sin sa vanishes at each atom .

The

**solution**for K = 1 / L has Ug ac sin ( sma / L ) ( 18 ) and vanishes for s = 0and s = N as required . The

**solution**for K = N / L = n / a = Kmax has Ug ac sin sa ;( 19 ) this permits no motion of any atom , because sin sa vanishes at each atom .
