The Fundamentals of Beta Decay: The Weak Force at Work

To understand the role of beta decay in thee cosmos, it i s necessary to first graph what this process is andhe whoty it events. Atomic nuclei are composted of proton ande neutrons.

Why Stellar Fusion Stops at Iron

For most of a star 's light elements, the primary source of energy is the fusion of light elements. Hydrogen fuses into helium, helium fuses into carbon and oxygen, and in massive stars, this continues up thee chain. Each fusion reaction reactione releases energy because the mass of thee product nucleus is slightly less than the sum of it parts - thee misg mass is converted intro energy acting to Einstein' s famoun, requatioun, difl1; FLT: 0; 3difl; E = mc 1button; 1button; FLTh; 3t; 3t; 3t; ths expth; thats extrains; thentrains extrains extravents.

This means that fusing iron anothers would have require an input energy, rather than recolasing it. Consequently, where a massive star developes a core of inert iron, fusion ceases.
