Webb29 nov. 2024 · Compared to n/γ/e − or light-ion-induced fission, the use of heavier projectiles allows to study fission of nuclei further away from the β-stability line, especially on the proton-rich side and in the region of superheavy nuclei, in addition to SF/βDF (see, sections 4.1 and 4.4 [16, 17, 86–88]). Webb24 maj 2015 · And there is another fact: Heavy nuclei show a proton-neutron imbalance, as nuclear forces are very short range, when a nucleus gains protons at some point it will need more than one neutron per proton to remain stable (as the Coulomb interaction grows quadratically with charge, the nuclear binding energy just linearly with nucleon number). unable to type numbers on laptop
