Ultracold neutrons

Neutrons that have a very low energy are called ultracold neutrons.

Their energy is similar to that of low temperature atoms.

Ultracold neutrons have speeds less than 7.5 m/s.

The mass of a neutron is 1.7 × 10 – 27

kg.

37. The maximum momentum of an ultracold neutron is about

A 4.41 × 10 – 27

kg m/s

B 1.28 × 10 – 26

kg m/s

C 4.41 × 1027

kg m/s

D 1.28 × 1026
