Answer to Question #333157 in Solid State Physics for Johannes Steven

Question #333157

Question 1​​​​​​​​​​​​

 Compute the net potential energy of a simple Na+Cl- pair. The equilibrium distance between the ions is 0.28nm. The potential energy due to repulsion between electrons is given by Ur= β/r8


Question 2

2.1α-Co has an hcp structure with lattice spacings of a= 2.51 Ao and c = 4.07 Ao, β Co is fcc, with a cubic lattice spacing of 3.55 Ao. What is the difference in density between the two forms?​​

2.2​ Sodium transform from bcc to hcp at about T = 23K. Assuming that the density remains fixed, and the c/ ratio isideal, calculate the hcp lattice spacing given that the cubic lattice spacing is  a' = 4.23 Ao in the cubic phase.      ​​​
