Energy in nuclear reactions
Transcript of Energy in nuclear reactions
Not only is the KE conserved but the momentum must be conserved too. (shown here in simplified case)
The energy that is released in nuclear reaction comes from mass defect in the reaction.
Often nuclear reaction require an incoming particle hitting a parent nuclei, then it releases a daughter(s) and an outgoing particle.
a + X Y + b
As well the amount of initial KE that is sometimes used to start the reaction must be conserved.
If the incident proton has a KE of 3.1 MeV what is the total KE of the products of the following reaction
p + Li He + alpha
Radon is unstable and has a half life of 3.8 days. If one radon decays via alpha particle, how fast is each fission product moving?
Rn Po + alpha
