← ScienceWhich outcome sharply CURTAILS nuclear fusion inside a collapsing star, if the increased density elevates electron capture rates on certain isotopes?
A)Neutron drip from unstable nuclei✓
B)Enhanced alpha particle emission
C)Increased neutrino radiation pressure
D)Endothermic nuclear transmutation
💡 Explanation
Neutron drip curtails fusion because the increased neutron number decreases the specific nuclear binding energy, therefore unstable nuclei form, rather than heavier, fusionable ones, causing a sharp drop off in available fuel.
