is made. <br></div><br><div style="font-style:normal;font-size:16px;background-color:transparent;font-family:bookman old style,new york,times,serif">But I read another statement <br><br>
</div><div style="font-style:normal;font-size:16px;background-color:transparent;font-family:bookman old style,new york,times,serif">''In
FP-LAPW approach the potential is expanded in two regions in such away
that (a) inside the atomic sphere it is in the lattice harmonics and (b)
inside interstitial region as Fourier
series'' which suggest that there is still shape approximation interms
of atomic sphere (MT) and Interstitial region.</div><div style="font-style:normal;font-size:16px;background-color:transparent;font-family:bookman old style,new york,times,serif">
