OSTI ID:5905640
The (O III) 51.8 micrometer line from four H II regions, M42, M17, W51, and NGC 6375A, was detected. Respective line strengths are 7 x 10/sup -15/, 1.0 x 10/sup -14/, 2.1 x 10/sup -15/ and 2.6 x 10/sup -15/ W/cm/sup 2/. Observations are consistent with previously reported line position and place the line at 51.80 +- 0.05 micrometers. When combined with the 88.35 micrometer data (O III) reported earlier, clumping seems to be an important factor in NGC 6375A and M42 and to a lesser extent in W51 and M17. The combined data also suggest an (O III) abundance of approximately 3 x 0.0001 sub n e' a factor of 2 greater than previously assumed.
