Question

What is the preferred mode of decay for nuclei that are neutron-rich? for nuclei that are neutron-poor?

Accepted Answer

Neutron-rich nuclei: neutron emission or beta decay
Neutron-poor nuclei: positron emission or electron capture

Answer

Neutron-rich nuclei: positron emission
Neutron-poor nuclei: beta emission or electron capture

Answer

Neutron-rich nuclei: alpha decay
Neutron-poor nuclei: gamma emission

Answer

Neutron-rich nuclei: alpha or beta decay
Neutron-poor nuclei: positron or neutron emission
