The de-Broglie wave length of the neutron beam of energy 150 ev is greater than the inter atomic spacing, hence it is suitable for diffraction experiment The de-Broglie wave length of the neutron beam of energy 150 ev is lesser than the inter atomic spacing, hence it is not suitable for diffraction experiment The de-Broglie wave length of the neutron beam of energy 150 ev is equal to the inter atomic spacing, hence it is suitable for diffraction experiments None of the above
