No additional actions are required for this. It is just due to the fundamental nature of the particles, which are described by quantum wave functions, that there is a finite probability that the particle-wave at the moment of the interaction just "leaks" thought the other particle-wave like a...

Quantum tunnelling is one of the few friends of physics that fusion has. It allows to overcome the electrostatic repulsion of 2 atomic nuclei when they approach close enough. Therefore, the classical electrostatic law does not apply here and there is no need of exponentially increasing energies...

Update: Ok, I think I got it. I found this interesting resource: http://web.utk.edu/~rpevey/NE406/lesson8.htm It looks like important is to know the first excited state of the nuclei after the scattering with an incident neutron with an energy E. This 1st excited state gives the Q-value, which...

You hit the point. I really wonder if the ITER community, with the exception of the US, really pays attention at such a critical aspect of the project. In my view, 3 critical aspects are mining the success of the project: 1. Stockpiles of tritium, vital as start-up inventory for the first...

Although a "competitive cost of electricity" is not a mandatory requirement for the step beyond ITER, i.e. DEMO, I guess no one will be interested do design and build a demonstration reactor that is not giving a couple of hundres of MW with a reasonable availability and reliability for a price...

I have been researching in the Forum, but I did not see anything conclusive about this: sorry if that was posted anywhere else here, I am new here :smile:. The energy loss of a neutron after an elastic scattering is a pretty straightforward calculation that can be done by hand. However, I am...
