A neutron with K.E equal to 0.04ev is called?
Correct answer: A. Slow neutron
- A. Slow neutron
- B. Thermal neutron
- C. Fast neutron
- D. Both (a) and (b)
Explanation
A neutron with a kinetic energy of a few hundredths of an electron volt has been slowed to roughly the thermal energy of its surroundings, so it is described as a slow neutron. Fast neutrons carry energies in the MeV range and are far less readily captured by a nucleus.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
