The Scattering of Helium Atoms by a Solid Can Be

question 88

Short Answer

The scattering of helium atoms by a solid can be used to gain information about the lattice of atoms, provided the wavelength of the helium atoms is comparable to the dimensions of the lattice.What is the wavelength, in picometers, of a helium-4 atom with a kinetic energy of 0.10 eV.(mass of ⁴He = 4.0026 amu; 1 amu = 1.67 * 10^-24 g; 1 eV = 1.602 * 10^-19 J; h = 6.626 * 10^-34 J.s)
