Essentially, I'm going from a unitless/normalized frequency of 2 to 80 mevs using [tex] \omega=2\sqrt{K_i/M}[/tex] where [tex]K_i[/tex] is 10.6 [tex]eV/\AA^2[/tex] and M is the mass of silicon. I should get approximately 80 mevs.. Not sure how I get there. I got to 1/s easily by using the mass of silicon in mevs/c^2 but that's about it
