Lattice Constants

your sample
a = A b = A c = A
a = deg. b = deg. g = deg.

CeO2 (a=5.411102A, cubic)
Si (a=5.430940A, cubic)

Symmetry

Primitive Face-Center Body-Center
A-Base-Center B-Base-Center C-Base-Center

Output Type

2q Q ( = 4psinq/l = 2p/d ) d ( = l/2sinq = 2p/Q )

This program is written in JaveScript, but it may not work in IE4.5 of Macintosh.
