In a bubble chamber experiment, the decay of a Σ+ particle intoa π+ particle and a neutron is observed when a 1.03 T magneticfield is applied perpendicular to the paths of the particles. TheΣ+ and π+ particles leave curved tracks of radii 2.01 m and 0.588 mrespectively. The rest masses are mΣ+ = 1189.4 MeV/c2 and mπ+ =139.6 MeV/c2. If at the moment of decay, the angle between themomentum of the Σ+ and π+ particles is 71.6°, what is the magnitudeof the momentum of the neutron? (Express your answer in units ofMeV/c.)
