The term p-process (p is for proton) is used in two ways in the scientific literature concerning the astrophysical origin of the elements (nucleosynthesis) originally . The p-process of stellar nucleosynthesis is aimed at explaining the production of the stable neutron-deficient nuclides heavier than iron that are observed up to.

Abstract the astrophysical p-process, which is responsible for the origin of the proton-rich stable nuclei heavier than iron, was investigated using a full. Ronment of r-process nucleosynthesis and a partial s- process origin for 107pd and p-processes are relatively well understood (neutron capture in agb-stars. This process is known as nucleosynthesis n + e + p this equilibrium produced about an equal number of protons and neutrons however.
