The Scattering of Helium Atoms by a Solid Can Be

Question 129

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)
