Problem

Electrons scattered from a nickel crystal produce their strongest first-order maximum at a glancing angle of

30^{\circ}

. Taking the interplanar spacing of nickel as

d=0.091\,\text{nm}

, determine the accelerating potential

V

through which the electrons must be passed to obtain this result. Use

h=6.626\times10^{-34}\,\text{J\,s}

m_e=9.11\times10^{-31}\,\text{kg}

and

e=1.6\times10^{-19}\,\text{C}
