. The de - Broglie wavelength of a neutron in thermal equilibrium with heavy water at a temperature T


The de - Broglie wavelength of a neutron in thermal equilibrium with heavy water at a temperature T (Kelvin) and mass m, is

A: 2h/√(mkT)

B: h/√(mkT)

C: h/√(3mkT)

D: 2h/√(3mkT)

Best Answer

EXPLANATION

At thermal equilibrium with heavy water at a temperature T(Kelvin), kinetic energy

E=3/2kT

The de - Broglie wavelength of a neutron of mass m in terms of kinetic energy is given as 

thermal equilibrium
