Nuclear Physics. Selected Topics 4 – Nuclear Reactions. The structure of nuclei can be changed by bombarding them with energetic particles. The changes are called nuclear reactions. As with nuclear decays, the atomic numbers and mass numbers must balance on both sides of the equation.

Nuclear Physics

Selected Topics

4 – Nuclear Reactions



Alpha particle colliding with nitrogen: with energetic particles.

Balancing the equation allows for the identification of X:

So the reaction is


“Target” particles may be bombarded with with energetic particles.

a, neutrons, protons, deuterons, gamma.

General scheme:

a + X  Y + b

Energy released:

Q = (Ma + MX – My – Mb).c2


Calculate with energetic particles.Q for some reactions.

Dm (in u) = 1.007825 + 7.016003 – (2)(4.002602)

= 1.8624 u = 17.3 meV

This energy is the kinetic energy of the products.


Calculate with energetic particles.Q for some reactions.

Dm = 1.007825 + 7.016003 – 7.016928 – 1.008665

= -.001765 u = -1.644 meV

The incident particle must have a minimum kinetic energy.

Here, m = 1.007825 u and M = 7.016003 u.
