Heavy metals in the gas phase are important in controlling the ionization of a cold dark cloud and hence the chemistry and finally the cloud evolution. Two of us (S. P. and R. C. D.) earlier suggested a fast radiative association mechanism to form MgNC and AlNC in TMC-1. We have conducted a sensitive search with the Green Bank Telescope (GBT ) for both species in TMC-1. The upper limit for the fractional abundance of MgNC is 1.2 × 10-11. We have run detailed models of the chemistry, which...[Show more]
