What is the purpose of toroidal magnetic field in tokamak fusion device?
From my understanding, pinching plasma to the center is the most important thing. And with Lorentz force, poloidal magnetic field from plasma current itself is pinching it to the center, this should ...

Can Stern-Gerlach experiments be conducted using nuclear spin?
If I used an element with completely paired outer electron shells, with a non-zero nuclear spin quantum number, could I conduct a nuclear Stern-Gerlach experiment?
It is known that the associated ...

Would modern nuclear warheads with tritium issues still produce an explosion of a smaller yield? [closed]
I want to know how tritium functions in today's nuclear weapons. I would specifically or theoretically like to know how these warheads' efficacy will be affected by the absence of tritium. If they did ...

Would it be possible to use Differential Pressure to create a fission reaction using a fluid enriched with fission fuel?
Would it be possible to use Differential Pressure to create a fission reaction using a fluid enriched with fission fuel?
(To preface this, this is all theoretical. I’ve been playing with the concept ...

Could antineutron and pion generate proton? [closed]
We need information and guidance regarding the possibility of two reactions: antineutron + pi+ -> proton and antiproton + pi+ --> neutron. The attached illustration indicates that such reactions ...

Beta-plus decay, a many-body problem?
In the beta-plus decay, a proton turns into a neutron, a positron, and a neutrino.
But the mass of a proton is less than a neutron. This of course indicates that an isolated proton is stabel against ...

What would be the effect of a nuclear explosion occurring on a beach or close to the surf?
So nuclear explosions in water tend to have different effects as water is denser than air and incompressible(and if I'm not mistaken it tends to absorb a significant amount of blast energy). But I ...

Breakdown of the Fermi gas model for the nucleus
One of the predictions of the Fermi gas model for the nucleus is that the most energetically favorable situation for a nucleus is to have $N=Z$, an equal number of protons and neutrons. Observing the ...

Relativistic mass of neutron almost at speed of light [duplicate]
What will be the relativistic mass of the neutron moving almost at the speed of light?
I am considering the relation Binding Energy, $$E = m c^2 \ .$$
Technically speaking, velocity would inversely be ...

Is it possible to construct nuclear power plant with element $\rm Be$?
Perhaps the most fundamental reaction in nuclear power generation is the one in which neutrons collide with 235 uranium, and I wonder if 235 uranium can be converted into 9 beryllium.
9 beryllium ...

How do you calculate the mass of diproton helium-2 nucleus?
I understand the diproton form of helium, helium-2 has a half-life of about a nanosecond. It seems safe to assume it's mass cannot be measured experimentally, yet I understand there is a way to ...

Where do the fission products go? [closed]
In Nuclear Fission, I see that the fragments contribute to most of the kinetic energy.
Does this mean the fragments actually come off the rods, travel in water while heating it up and then settle ...
