Stellar fusion involves protons becoming neutrons, which means ejecting a positron. Positrons annihilate electrons. This must deliver some energy in stellar fusion. But how much of the energy from stellar fusion comes from this positron-electron annhilation?

    $\begingroup$ Wich kind of fusion are you referring to? $\endgroup$ Commented May 6, 2016 at 11:15

    $\begingroup$ @lemon. I'm hoping English isn't your native language or I'll really be sad. The OP clearly asked for the fraction of all released energy attributable to proton decay. $\endgroup$ Commented May 6, 2016 at 11:37

    $\begingroup$ You're not entirely correct, either one. Yes, I do mean a fraction (I think more in percentages, but tomato/tomato). However, it's not the proton decay itself, but the positron-electron annihilation that interests me. Please be nice to each other. $\endgroup$ Commented May 6, 2016 at 13:47
