Quantity conserved in nuclear reaction
WebFor spinless particles and central forces the orbital angular momentum ℓ is a conserved quantity, for reactions with particles, whose spin is ≠0 only the total angular momentum J is conserved. For two-particle nuclear reactions we thus have WebUsually, but not always, Energy is a conserved quantity as the other answers have explained. In the BB framework where space expands, or in the dual 'shrinking matter' (almost dual) (comoving framework), the ratio of matter/space is not invariant and energy is not conserved, i.e. Nöether's Theorem does not apply.

Alpha decay occurs spontaneously only if the daughter and 4 … WebAug 10, 2024 · Exothermic and endothermic reactions can be thought of as having energy as either a product of the reaction or a reactant. Exothermic reactions give off energy, so energy is a product. Endothermic reactions require energy, so energy is a reactant. Phase changes, discussed in the previous section 7.3, are also classified in a similar way.
