Are there spectra that "prove" that measured energy excesses came purely from deuterium-tritium fusion reactions at the NIF during ignition events?
More energy was produced than was supplied by ultraviolet (UV) lasers (creating x-rays in the gold chamber wall to compress the spherical hollow capsule creating a dense, high-temperature, high-...

Could lithium deuteride sustain a "cold" chain reaction?
When Lithium 6 absorbs a neutron (thermal or not) it reacts forming an alpha particle and a tritium. The formed tritium has an average kinetic energy of 2.5 MeV. That kinetic energy is way higher than ...

Improved estimate of density of free neutrons in solar core
In an answer to this question:
Free neutrons in the sun's core?
I made a very rough attempt to estimate the density of free neutrons in the solar core. There is some non-zero rate for production ...

Nuclear fusion reactors and neutrons
The majority of energy produced by nuclear fusion is harnessed by neutrons or protons that split out from the product.
Given the dominant fusion method today is Deuterium + Tritium which produces He ...

Can neutron magnetic moment be used to slightly deflect the neutrons to not hit the tocamac lattice at a really small angle?
Can neutron magnetic moment be used to slightly deflect the neutrons to not hit the tocamac lattice at a small angle? So part of the moment is spent to change its velocity vector orientation?

What defines Fusion-Evaporation Reactions in Nuclear Physics?
A bit of a general question I know; but I would like to understand a bit more about the topic.
The situation is an alpha beam is incident on an Aluminium-27 target, which ejects a neutron and leaves a ...

Are the presense of neutron reflecters the only difference between a hydrogen bomb and a neutron bomb? [closed]
From what I understand, a hydrogen bomb usually has neutron reflectors, like graphite, to increase the yield of the explosion. A neutron bomb does not have those reflectors. Are there any other ...

As neutrons are more massive than protons, does the Sun increase its mass while fusioning elements?
Where is the mass coming from when neutrons are produced from protons in the Sun?
If a positron is made, will it possibly annihilate with an nearby electron?

Using a Neutron Poison In $D$-$T$ Fusion Reactors to Capture Neutrons
One of the major problems of the $D$-$T$ fusion reaction is that it releases a 14MEV neutron. In large numbers, these neutrons irradiate the chamber walls and wreak havoc on the metallic lattice, ...

'Forces' enacted by hot neutrons in fusion bomb - Pauli exclusion
Are Pauli exclusion 'forces' on a neutron 100% electromagnetic (Lennard-Jones seems more acute relationship compared to electrostatic force)
If so does that neutrons have two forces between them - '...

Ultra Cold Neutrons in a Bottle Question
If you take a large amount of ultracold neutrons and confine them in a bottle would they then decay into protons and then fuse because they are so tightly condensed that the protons, once neutrons, ...

How can you determine how much neutron shielding is necessary for a given neutron source?
Trying to make a fusor at home and I was wondering if there is an industry standard or perhaps an equation to determine how and what type of neutron shielding is necessary to protect against the high ...

Free neutrons in the sun's core?
In the standard description of proton-proton fusion, the first step of the interaction proceeds through the unbound diproton $\rm^2He$:
$$
\begin{aligned}
\rm p + p &\to \rm {}^2He^*
\\
\rm ^2He^* ...
