I know the reason, but not everybody agrees with it. They think it's just a poor excuse to place another link to the prequels. Anyway this is the official reason (you can hear this on one of the dvd commentary's) You see when Anakin became Darth Vader, Anakin's Jedi spirit was lost. It now appears to Luke in this younger form because Luke has allowed Anakin to fulfil his prophecy and regain his former identity, which takes the physical shape and form that it had before he turned to the dark side. If the older force ghost was used, it should really, considering Anakin's human injuries, be scarred, limbless and deformed. It's also possibly because Sebastian Shaw might appear to be too old in the scene, since Anakin would likely be about 46 years old while Sebatian Shaw was already over sixty years old by the end of Return of the Jedi.
