Observations of the (J,K) = (1,1) ammonia transition toward the suspected exciting sources of 12 regions with molecular or optical outflows are presented. In nine of these regions, ammonia emission was detected and mapped. The spatial coincidence of the high-density gas in the proposed exciting sources in five of the mapped regions supports the identification as exciting sources. A new location is proposed for the outflow exciting sources of L1524 (Haro 6-10) and HH 38,43. Also, in L1448, a radio continuum source and an unusually strong H2O maser coinciding with the maximum ammonia emission is detected. It is proposed that this region is the site of very recent star formation. 73 refs.
