Rapid proton capture is supposed to be responsible for the synthesis of a number of proton-rich nuclei. This process of hydrogen burning is considered here for mass elements, the atomic numbers of which range from Z = 10 to Z = 20. The possible site for this process is assumed to be the outer envelope of the supernova at a proton number density (np) ranging from np = 1022cm-3 to np = 1028cm-3 at temperatures in the range of T = 2 - 3×109K. The capture path is determined by considering that a dynamical equilibrium between (p,γ) and (γ,p) reactions exists between the reacting nuclei. It is suggested that the rapid proton-capture reactions are responsible for the production of a number of nuclei in the range A ⪉ 40 during supernova outbursts.
