To determine

To explain: The reason for the statement that proton decay is restricted inside the nuclei only, not in its free state.

Expert Solution & Answer

Answer to Problem 1RQ

Solution:

The rest energy of protons is less than the rest energy of neutrons, therefore, proton decay takes place in nuclei only because the nucleus will provide additional energy to overcome this energy barrier.

Explanation of Solution

Introduction:

Beta decay is referred to as the transformation of protons into neutrons and vice-versa. This decay is further categorized into two different types depending upon the formation of these sub-particles.

Beta plus decay: In this decay, a proton is transformed into a neutron along with the formation of a positron and a neutrino.

Beta minus decay: In this decay, a neutron is transformed into a proton along with the formation of an electron and an antineutrino.

Explanation:

A light mass particle cannot convert into a heavy mass particle in a free state, and the mass and energy of a neutron is greater than that of a proton. Therefore, the transformation is not achieved in free state of a proton. This additional mass and energy are either provided by a gamma-ray photon or by the energy of the nucleus.

Since the beta transition takes place in between the isobars (atoms that have the same atomic masses). For example, the transition of potassium into argon taking place in a human body is capable of producing approximately 200,000 positrons in a minute.

The reaction is as follows:

1940K→1840Ar++10e+00v

Since the proton itself is not able to decay into another sub-particle that has a greater mass and higher energy, therefore, the binding energy of the electrons that are associated with isobaric atoms supplies the extra energy that is required for the decay process.

Conclusion:

The additional rest energy of neutron is provided by the nucleus during the beta plus decay, therefore, this decay always takes place in nuclei.
