[Wien] Volume optimization of Sn

[shamik chakrabarti]

Dear Dr. Tran,

                   Thank you for your reply. It is obvious that I have got
the wrong structure of Sn. In this regard can you please send me the struct
file of Sn on which you have worked in your paper.

Looking forward to listen from you.

with regards,
