Thermal neutron spectrum

  1. Apr 3, 2014 #1
    The most probable velocity of thermal neutrons can than be approximated by the Boltzmann constant and is given by the following:

    v = sqrt (2kT/m)

    k is the boltzmann constant
    T is the temperature
    m is the mass of the neutrons

    My question is why is the above equation not the following

    v= sqrt(3kT/m)
