Ask Hiroshima and Nagasaki.
In alphabetical order.
That's fissed, not fused.
I stand corrected, because I done forgetted.
Those are fission. Fusion bombs don't fuse uranium. They use a fission bomb to fuse Lithium.
Oh, they do, but not as the primary or secondary. You can wrap depleated uranium around the core to capture fast neutrons that are leftover from the rest of the process. Changing the number of layers is how you can dial in a desired yield.
Fusion bombs use a fission bomb to fuse Hydrogen, which is why they're called H-bombs.
Sorry I meant Lithium Deuteride.
6Li2H
https://en.m.wikipedia.org/wiki/Thermonuclear_weapon
I mean if we really want to be technically accurate here, the lithium is just a moderater for the hydrogen isotopes to fuse.
But for me it gets fuzzy when looking at the reaction.
LiD is 4 protons, 8 neutrons. Add a new neutron, and bam, you have 4 protons and 9 neutrons. But that's where it gets weird to me. The lithium needs to decay or something into a tritium and dueterium which forces the tritium to fuse with the existing dueterium in the LiD molecule? Clearly the neutron has enough energy to transfer into one of the atoms to increase the chance of tunneling actually occuring.
The only real purpose of the lithium deuteride is that it's a dry, shelf-stable, room-temperature fuel. The very first hydrogen "bomb" (actually a building-sized device) used supercooled liquid hydrogen as the fusion fuel, but this was obviously not practical for a deliverable bomb.
For that matter, even the Nagasaki bomb ("Fat Man") didn't use Uranium at all - its fuel was Plutonium.
