This sequence proceeds as follows: A carbon-12 nucleus captures a proton and emits a gamma ray, producing nitrogen-13.

The first step in all the branches is the fusion of two protons into a deuteron. As the protons fuse, one of them undergoes beta plus decay, converting into a neutron by emitting a positron and an electron neutrino (though a small amount of deuterium nuclei is produced by the "pep" reaction, see below): p + p → 1D + e + ν e The first step in all the branches is the fusion of two protons into a deuteron.
