WebHelium is an element, so to make an element you have to combine protons and neutrons which is much much harder than it sounds. There are only 2 environments that commonly make elements. First is inside stars where the pressure and heat are unimaginably high that the protons and neutrons flu around in massive soup until they can stick to each other. WebOct 2, 2015 · 27. It's boron-10 that is the good neutron absorber. Boron-11 has a low cross section for neutron absorption. The size of the nucleus isn't terribly relevant because neutrons are quantum objects and don't have a precise position. The incident neutron will be delocalised and some part of it will almost always overlap the nucleus.
WebFeb 28, 2024 · Helium has seven known isotopes, ranging from He-3 to He-9. Most of these isotopes have multiple decay schemes where the decay type depends on the overall energy of the nucleus and its total angular momentum quantum number.
