Abstract: We report spatial distributions in CCS and HC3N towards a CCPR(Carbon-Chain Producing Region) candidate core, L1147, where CCS peaks are displaced from that of HC3N. Their fractional abundances relative to H2 are around 10–9. We conducted chemical reaction network simulations to understand the distributions of CCS and HC3N, and found that the ratios of “CCS/HC3N” and “NH3/CCS” would be well reproduced in early phase under the H2 number density of 1×104 – 1×105cm–3.
