Beta emission momentum problem

In summary, the conversation discusses the disintegration of C14 via b-emission, with a reaction energy of 0.155 MeV and a b-particle emitted at 0.025 MeV in a direction 135° from the recoil nucleus. The momenta of the three particles involved (b-particle, 14N, and antineutrino) are also mentioned, with a question about the effect of the antineutrino. The suggested solution includes the equation Q=P^2/2m for both the nitrogen and beta particles, but it is unclear how the antineutrino affects this equation.

Homework Statement



C14 disintegrates by b-emission with a reaction
energy (q value) of 0.155 MeV. A b-particles with an
energy of 0.025MeV is emitted in a direction at 135°
to the direction of motion of the recoil nucleus. Then
the momenta of the three particles (b = V, 14N)
involved in this disintegration in MeV/c units will
be. (where, c is speed of light in vacuum) (M0 = 0.511
MeV/c2 )

Homework Equations



Q=Total Energy. therefore Q= 0.025+ energy of nitrogen atom + antineutrino

The Attempt at a Solution


Q=P^2/2m(nitrogen) +p^2/2m(beta particle)

I am confused about the effect of the antineutrino. Can you please explain that?
 

Related to Beta emission momentum problem

1. What is the Beta emission momentum problem?

The Beta emission momentum problem is a phenomenon observed in nuclear reactions where the total momentum of the particles involved in the reaction does not add up to zero, violating the principle of conservation of momentum.

2. How does the Beta emission momentum problem occur?

The Beta emission momentum problem occurs when a nucleus emits a beta particle, which is a high energy electron, resulting in an imbalance of momentum. This is because the beta particle carries away a significant amount of momentum, causing the total momentum of the system to no longer add up to zero.

3. What impact does the Beta emission momentum problem have on nuclear reactions?

The Beta emission momentum problem can have a significant impact on nuclear reactions. It can affect the energy distribution and angular distribution of the particles involved, leading to inaccuracies in calculations and predictions.

4. How do scientists address the Beta emission momentum problem?

Scientists address the Beta emission momentum problem by using sophisticated mathematical models and techniques to accurately account for the momentum of all particles involved in the reaction. They also conduct experiments and make observations to validate their calculations.

5. Can the Beta emission momentum problem be completely eliminated?

While the Beta emission momentum problem can be mitigated by using advanced calculations and experimental techniques, it cannot be completely eliminated. This is due to the inherent nature of beta emission and the unpredictability of nuclear reactions.
