Transcribed Image Text:1. The mass of a neutron is 1.67 x 10-27 kg. Convert this to units of MeV/c². Calculate
the velocity of neutrons required to perform neutron diffraction of a specific crystal,
whose interatomic spacing is of the order 2A. What is the total kinetic energy for
these neutrons? What is its relativistic energy?
2. From scattering experiments, it is found that the nuclear diameter is of the order of
10-15 m (1 fm). The energy of an electron in 8-decay experiment is of the order of
a few MeV. Use these data and the uncertainty principle to show that the electron
is not a constituent of the nucleus.
3. A free electron has wave function (x,t) =sin(kxwt). Determine the electron's
de Broglie wavelength, momentum, kinetic energy and speed when k = 50 nm-¹
