Öz In section 3.2 on page 767, in numerical calculations there is density (ρ) in equations of debye temperature, longitudinal and transverse elastic wave velocities. Actually we used density as follows:                                                                                                                    here M molecular mass, NA  Avogodro’s number, V is volume (V= a3, a lattice parameter),  Z= 1.  But  in calculations we used Z=4 by mistake.  By using  Z=1 we obtained correct numerical values  for Table 3 as given following.
