He shell production of coincides with initial abundances in that region, and the total shell production and enclosed mass of the production site increases with explosion energy. In both isotopes we see moderate destruction of initial abundances in the core and a moderate increase in final abundances in the interior shells. However, the nucleosynthetic production site trends in more closely resemble those of and with a two-peak production pattern in the He shell. Though the site of the dip separating the two peaks is the same here, in contrast to the above the abundance of the outer of the two peaks is less than that of the inner for . The energy trends in production site for are similar to those of and , but the trend in final explosive yields with explosion energy are much weaker, as seen in Figure \[fig:yield\_scexp\].

There is a weak trend in production with explosion energy for , but the final yields depend on a more complicated interplay of the explosion parameters. Although it is primarily made in the core, more massive progenitors and higher explosion energies can lead to increased production in the middle/outer C/O shell. This change in production site patterns with
