| 31. | The operation has to be performed at low pressure, as the stability of atomic hydrogen at atmospheric pressure is insufficient.
|
| 32. | The Holmberg diameter is 1880 parsecs, but neutral atomic hydrogen gas extends more than eight times further out in a disk.
|
| 33. | The ALFALFA survey is a blind extragalactic survey in neutral atomic hydrogen ( HI ) utilizing the ALFA at Arecibo Observatory.
|
| 34. | From measurements of the neutral atomic hydrogen in the galaxy, it has been found that the disk of NGC 3109 is warped.
|
| 35. | As atomic hydrogen absorbs and emits energy in the form of electromagnetic radiation, it oscillates between higher and lower states of excitation.
|
| 36. | The emission spectrum of atomic hydrogen is divided into a number of "'spectral series "', with wavelengths given by the Rydberg formula.
|
| 37. | The aim of his PhD research was to make a gas of atomic hydrogen, which could become the world's first quantum gas.
|
| 38. | The satellite has a thin oxygen atmosphere that includes O, O 2, and possibly O 3 ( ozone ), and some atomic hydrogen.
|
| 39. | He also discovered atomic hydrogen, which he put to use by inventing the atomic hydrogen welding process; the first plasma weld ever made.
