Estimate the kinetic energy of the neutrons in a neutron beam that can be used to probe lattice structures with an interatomic spacing of 0.3 nm. The mass of the neutron is 1.675 x 10-27 kg.
To estimate the kinetic energy of the neutrons, we use the de Broglie wavelength relation: \[ \lambda = \frac{h}{p} \] where: - \( \lambda \) is the wavelength of the neutron, - \( h _____ ________ ______ _______ ___ __________ __________ _______ ______ _______ ___ _____.
