German term or phrase: kernwasserstoff
In a patent relating to the production of mixed oxides, "Kern- oder Reaktionswasserstoff" is added to evaporated silicon tetrachloride. Is this nuclear hydrogen, core hydrogen or something else?

English translation:atomic hydrogen
Explanation:
I suspect it is hydrogen in it's uncombined form, i.e. just H not H2. Chemists sometimes calls it 'in statu nascendi'

From Webster\'s:
atomic = having its atoms in an uncombined form [atomic oxygen]

nascent = (Chem.) designating or of the state of an element just released from a compound and having unusual chemical activity because atoms of the element have not combined to form molecules [nascent chlorine]

As you can see \'atomic\' can be equivalent for this \'Kern-\' and nascent for \'Reaktions-\' but both means essentially the same

pure hydrogen


Explanation:
It can only surmise they mean pure hydrogen (the evaporation of the SiCl4 is probably a purification step). There is no such thing as nuclear hydrogen (a proton?). Reaction hydrogen (direct translation, no google hits) is presumably hydrogen from a reaction (i.e. pure).

Core hydrogen


Explanation:
The only meaning I have encountered for Kernwasserstoff is core hydrogen, that is hydrogen located in a core, as in a star. Possibly it could also mean hydrogen arising from some kind of core. Of course we can't tell whether any kind of core is involved here without knowing more context.

Reaktionswasserstoff could well be translated as nascent hydrogen, but not with certainty without knowing more context. Nascent and atomic hydrogen are not synonyms, rather nascent hydrogen is hydrogen formed in a reaction and used as it is formed, implicitly atomic, because the whole point with using nascent hydrogen is to obtain the more reactive atomic form.
