Using a semiempirical nuclear fragmentation model developed at NASA Langley Research Center (NUCFRG2), we analyze one nucleon removal cross sections in terms of nuclear and coulomb cross sections. We find there is a need for structure effects in light and medium nuclei. The interesting cases of one neutron and one proton removal cross sections in {sup 40}Ar and {sup 56}Fe will be discussed. Within a simple single particle shell model picture, both these nuclei can be described by 2p-2h states with respect to sd and fp shells, respectively. Experimentally, one neutron removal cross sections for these nuclei are approximately three times larger than one proton removal cross sections reflecting to the neutron shells to be {open_quotes}farther{close_quotes} than proton shells.
