Abstract
We reexamine the problem of n-n̄ oscillations for ultracold neutrons confined within a trap. We show that, for up to 103 collisions with the walls, the process can be described in terms of wave packets. The n̄ component grows linearly with time, with the enhancement factor depending on the reflection properties of the walls.
