Fusion occurs when two atoms slam together to form a heavier atom, like when two hydrogen atoms fuse to form one helium atom. This is the same process that powers the sun and creates huge amounts of energy—several times greater than fission. It also doesn’t produce highly radioactive fission products. how many weeks between christmas and easter

WebThe amount lost will massively outweigh the helium produced through fusion (limited by the mass of DT fuel used). DV82XL • 2 yr. ago. Yes, but not in any significant quantity using any apparatus that would fit on Earth. You basically need a star for that. Simon_Drake • 2 yr. ago. In theory, yes. WebIf a neutron star has extra mass beyond this dumped on its surface (say, because it is orbiting an ordinary star, and that star accretes mass onto the NS), they can explode in a violent way.

How can neutron stars undergo helium fusion

WebIn heavier stars, the oxygen can in turn fuse with the helium to make neon.) Helium fusion produces only 9% as much energy per kilogram as hydrogen fusion, so energy-wise, the Sun continues to be mainly a hydrogen reactor. 90% of its luminosity still comes from burning hydrogen. However, it is the helium surrounding the core which now dictates ... WebWhen a neutron is captured by a uranium-235 nucleus, the outcome may be represented by the nuclear ...
