Report Thermal neutrons are neutrons that move at speeds comparable to those of air molecules at room temperature. These neutrons are most effective in initiating a nuclear chain reaction among isotopes. Calculate the wavelength (in nm) associated with a beam of neutrons moving at 6.93 x 10 m/s (mass of a neutron = 1.675 x 10-27 kg). Enter your answer in...
