The most proable kinetic energy of thermal neutrons at a temperature of T Kelvin, may be taken equal to kT, where k is Boltzmann constant. Taking the mass of a neutron and its associated de-Broglie wavelength as m and lambda_B respectively, state the dependence of lambda_B on m and t.

Energy of a particle at absolute temperature T is of the order kT. Calculate the wavelength of thermal neutrons at 27^(@)C . Take mass of neutron = 1.67 xx 10^(-27)kg, h =6.6 xx 10^(-34)Js and k = 1.38 J " mol"^(-1)K^(-1) .
