Horia Hulubei
The numerical challenge associated with the timedependent approach to the general problem of the decay of a
metastable state
by quantum  tunneling is discussed and meth ods towards its application to concrete problems are presented. In particular, different artificial boundary conditions were implemented in order to reduce the reflections of the wave packet at the numerical boundaries. They are illustrated and optimized for the deep  tunneling case of ground  state proton decay.
