(c) (i) In an x-ray diffraction experiment, x-rays of wavelength 0.0586 nm diffract from a nickel crystal at an angle of 13.60. Given that the lattice constant of nickel is 0.3524 nm, determine the miller indices of the planes from which the diffraction occurs. (Note doki = Truk4?) [2] (1i) A neutron beam of kinetic energy 40 meV is diffracted at the (100) plane of cubic crystal (dar=0.314 mm). Calculate the angle at which the 1st order Bragg peak is observed (neutron mass = 1.6 x 1027 kg). [2] T
