We consider the decay dynamics of bosonic atoms with delta-function interaction in one dimensional potential. We examine two model situations: (i) decay of metastable several-particle states and (ii) dynamics in a well of finite depth with parameters changing in time. We treat the problems perturbatively and fully numerically. In particular we focus on the time dependence of the mean atom number in the traps.
