[QUOTE="duchuy, post: 6455082, member: 686238"] [B]Homework Statement:[/B] Formula demonstration [B]Relevant Equations:[/B] Ed = [Mn(X) – (Mn(Y) + m(e))] c2 Hi, I understood that to calculate the available energy in these two reactions could be calculated from Ed = [Mn(X) – (Mn(Y) + m(e))] c^2, but when I have to change[B] use the[/B] [B]atoms' mass instead of the nucleons' mass[/B], it gives out two different formulas : Ed = [M(X) – M (Y)] c2 for β- Ed = [M(X) – (M(Y) + 2 m(e))].c2 for Ed = [M(X) – (M(Y) + 2 m(e))].c2 for β+ Can someone please explain to me why for β-, the mass of the electron isn't taken into consideration whilst for β+, we'd have to add the mass of two electrons ( when we are using the mass of the atom to calculate ). Sorry if I have misused any vocabulary, I translated this from french. Thank you so much for your help! [/QUOTE]
