Description
The phenomenon of particle tunnelling through a modified cubic potential is studied by focusing on the transition amplitude instead of the wavefunction, as is done in the usual WKB approach. The Green function, decay width and transmission probability for the tunnelling of localized wavepackets are computed within this framework. (author)
