Question: ( 1 0 pts ) An electron passing through a potential difference V O = 6 4 V is used to perform an electron scattering

(10 pts) An electron passing through a potential difference VO=64V is used to perform an electron scattering experiment on a cubic crystal, as shown in the figure. If the maximum scattering occurs at =30, calculate the lattice spacing L of the crystal. (Hint: one can use hc=1240(eV) and the rest energy of an electron (:mec2=0.5106(eV).
