A Beam of Neutrons (M = 939

question 54

Multiple Choice

A beam of neutrons (m = 939.6 MeV/c²) of momentum 12 keV is passed through a single slit of width 0.10 nm.As a result of this,the neutron beam acquires an uncertainty in the component of the momentum that is transverse to the beam direction.If the distance between the slit and a projection screen onto which the neutrons are projected is 1.5 m,what is the expected width of the neutron distribution on the projection screen in the transverse direction?

• A) 155 cm
• B) 12 cm
• C) 25 cm
• D) 50 cm
