Slow-moving neutrons, or thermal neutrons, have velocities around 2200 m/s at room temperature. Using the de Broglie wavelength formula, their wavelength is approximately 1 angstrom (10⁻¹⁰ m), which is similar to atomic spacing in crystals and is crucial for neutron diffraction and scattering experiments.
Wavelength of slow moving neutrons is about?
