| 1. | In the context of nuclear reactions this is called a Coulomb barrier.
|
| 2. | Is this the Coulomb barrier ? and 2 . why does it release energy?
|
| 3. | It is called the Coulomb barrier.
|
| 4. | The nuclei do not actually have to have enough energy to overcome the Coulomb barrier completely.
|
| 5. | The absence of the Coulomb barrier enabled the neutron's discovery by James Chadwick in 1932.
|
| 6. | The Coulomb barrier is smallest for isotopes of hydrogen, as their nuclei contain only a single positive charge.
|
| 7. | From this distribution, the fraction of particles with a velocity high enough to overcome the Coulomb barrier can be determined.
|
| 8. | Which is the probability of an s-wave nuclide to penetrate the Coulomb barrier, according to the WKB approximation.
|
| 9. | The Coulomb barrier causes the cross section to have a strong exponential dependence on the center-of-mass energy.
|
| 10. | The neutrino is not repelled in anyway, so there's not really a'coulomb barrier'style activation energy.
