I have a very hard time finding information about $HCCO$. I don't even know what it's name is.

I'd like to know what its main features are, where it shows up and/or what it's used for?

This does not seem to be a physics question (except in the snark sense of calling chemistry an effective theory of physics). There is a area 51 proposal for chemistry making good progress. – dmckee Jan 27 '12 at 17:58
@dmckee: I know, I'm commited. – NikolajK Jan 28 '12 at 3:22
There is a database here, however it doesn't find $HCCO$ in this case. – NikolajK Jan 30 '12 at 14:55

From this Google book hit, I think it's called a ketenyl radical. Searching ketenyl radical seems to bring up hits with the same compound formula.

Incidentally, it wasn't that hard to find by searching hcco compound. Ninth hit, I think...
