Calculate the kinetic energy of two alpha particles

Click For Summary
SUMMARY

The discussion focuses on calculating the kinetic energy of two alpha particles produced from the reaction of lithium-7 capturing a proton. The relevant nuclear reaction is represented as 3Li7 + 1H1 → 2He4 + 2He4. To determine the kinetic energy, one must calculate the mass difference between the reactants and products, which translates into energy according to Einstein's mass-energy equivalence principle. The mentor emphasizes that the total energy, assuming no gamma radiation, is converted into the kinetic energy of the alpha particles.

PREREQUISITES
  • Understanding of nuclear reactions, specifically fusion processes.
  • Familiarity with mass-energy equivalence (E=mc²).
  • Basic knowledge of atomic mass units (u).
  • Ability to perform mass calculations and conversions.
NEXT STEPS
  • Study the principles of nuclear fusion and decay.
  • Learn how to calculate mass defect and binding energy in nuclear reactions.
  • Explore the concept of kinetic energy in particle physics.
  • Investigate the role of gamma radiation in nuclear reactions.
USEFUL FOR

Students of physics, particularly those studying nuclear physics, as well as educators and anyone interested in understanding the energy transformations in nuclear reactions.

if lithium 7 3 captures proton, it is divided into two alpha particles. Calculate the kinetic energy of the alpha particles. the proton energy can be neglected and the mass of the nucleus of Li is 7,01601u.
I only know how to write the equation: 3Li7 + 1H1 → 2He4 + 2He4

Can anyone help me? How do i calculate the kinetic energy of the alpha particles??
p.s sorry I am a beginner in physics and I am trying really hard to solve these kind of problems.

Simple solution: Add the rest masses of both sides of the equation. The difference is then energy. Assuming no gamma rays, the energy becomes kinetic energy of the two alpha particles.
