Name the parameters that characterise a unit cell .

1.	Name the parameters that characterise a unit cell .
Answer» A unit cell is characterised by i) its dimensions along the three edges , a, b, and c . ii) angles between the edges , `alpha` (between b and c) `beta` (between a and c ) and `gamma` (between a and b) . Thus , a unit cell is characterised by six parameters a , b , c, `alpha , beta and gamma` . Illustration of parameters of a unit cell :
