My question is about an old SF short story from a compendium of them which I had as a child back in 1965/1966.
Story is about a sleeper ship traveling to a nearby star with two guys on board who split shifts being conscious and in hibernation. As they approach the end of their journey a starship from Earth approaches them, it is FTL capable utilizing newly-discovered technology of electron psychology, or "addiclenendar", to achieve FTL travel. For some reason I thought it was Van Vogt, but haven't been able to find a story of his that matches this storyline.
