10 Questions
What is the first product formed by fusing two helium-4 nuclei?
Beryllium-8
Why can fusion reactions not produce nuclei heavier than iron-56?
The fusion reactions become unfavorable
How is a heavier isotope of an element produced in neutron capture?
By adding a neutron to the seed nucleus
What process occurs when an unstable isotope undergoes beta decay?
Increase in atomic number
Why do different pathways, such as neutron or proton capture, become necessary for the synthesis of heavier nuclei?
The nuclear binding energy decreases
What is the main difference between the slow neutron capture (s-process) and the rapid neutron capture (r-process)?
Rate of neutron capture
Which process is associated with a supernova based on the information provided?
Rapid neutron capture (r-process)
Why is proton capture (p-process) difficult to occur naturally according to the text?
Strong nuclear force repulsion
Which type of nucleosynthesis is proton capture (p-process) associated with?
Supernova nucleosynthesis
In which scenario does a 0−1β decay almost always occur before another neutron can be captured?
Slow neutron capture (s-process)
