Can someone please try to help me with this. I have a bcc structure and the question is ''Clearly indicate the unit translation vectors and state their value in Å.
I have attached the sketch :
http://img440.images.../picture3lh.jpg
are those t1,t2,t3 translation vectors?
I know the cell parameters are:[tex] a=b=c=31652\AA[/tex]
Are these correct values of t1,t2,t3 then?
[tex] t_{1}=(-\frac{a}{2},\frac{a}{2},\frac{a}{2})=(-15826,15826,15826)\AA ?[/tex]
and similarly the rest?
And one question more. We need to calculate the volume of the conventional unit cell and volume of the primitive unit cell, is this correct?
[tex] V_{conv}=a^{3}=3171\AA^{3}[/tex]
[tex] V_{primitive}=\frac{V_{conv}}{2}}=1585.5\AA^{3}[/tex]
Is the plane which has the highest degree of compaction (101)??
and the deree of compaction[tex] \frac{\sqrt{2}}{a^2}}[/tex]???
It there anything special with a primitive cell? (how would you answer that question)?
