Abstract: The CCP radical (X$^{2}\Pi_{r}$) has been detected in the circumstellar gas of IRC+10216, the fifth phosphorus-bearing molecule identified in interstellar space. Four rotational transitions of this species were observed using the Arizona Radio Observatory (ARO) 12m telescope on Kitt Peak at 2 and 3 mm. Each transition consists of lambda-doublets, which are well-separated in frequency in IRC+10216; five of these eight possible lines of CCP were clearly detected, while the remaining three were contaminated by stronger emission from other species. The column density derived for CCP was N$_{tot}$ = 1x10$^{12}$ cm$^{-2}$ and T$_{rot}$ = 21 K. Modeling of the line profiles suggests that CCP arises from an extended shell with a maximum radius of 40". The abundance of this radical, relative to H$_2$, is f = 1x10$^{-9}$ - roughly comparable to that of PN and CP in this source. CCP may be produced from radical-radical reactions of CP, or ion-molecule chemistry involving P$^+$ and HCCH. The identification of CCP is additional evidence that phosphorus chemistry is active in carbon-rich circumstellar gas.
