River, there are plenty of studies of atomic hydrogen. For example, it is very important in astronomy, because in the vacuum between the stars, not only is hydrogen the most abundant element but the distance between adjacent atoms is enough to prevent atomic hydrogen all being converted into diatomic hydrogen via interatomic collisions. But, if they do not collide, they are not statistically at thermal equilibrium, and therefore bulk properties such as temperature and physical state are undefined. As to the study of how atomic hydrogen behaves, you are deluding yourself if you think this has not been studied. Below are 3 examples of papers, picked at random from the internet, on rate constants for the reaction of atomic hydrogen with various species: http://link.springer.com/article/10.1007/BF00905740#page-1 http://link.springer.com/article/10.1007/BF02084201 http://www.jstor.org/discover/10.23...id=2129&uid=2&uid=70&uid=4&sid=21102572841971 Furthermore the spectrum and structure of atomic hydrogen is by far the best understood of any atom in the whole of physics and chemistry, as it is the only system for which Schrodinger's equation can be solved exactly. So if you want to make a new contribution in this crowded field, you are going to have to be far, far more specific as to what you think you are going to add to the sum of human knowledge. Vague notions of trapping individual atoms behind a barrier(unspecified) in order to study something or other (unspecified) are simply going to make people think you do not know what you are talking about - a conclusion that a number of readers are evidently already reaching..
