Some people would apply the term sublimation to the process solid - 
vapour - solid (the phenomenon you see when you gently warm iodine 
crystals on a watch glass covered by an inverted glass funnel).  I don't 
subscribe to this view,  However ..

I have *never* seen the word deposition used to describe the vapour - 
solid change (except perhaps in it's wider generic sense) .  I have come 
across electro-deposition and other terms but nothing like (or 
including) deposition to describe the gas/vapour - solid change.  I'd 
appreciate a reference ...

PS are you confident regarding the distinction between "gas" and "vapour" ?
