abstract = "We analyze the effects of inelastic scattering on the tunneling time theoretically, using generalized Nelson's quantum mechanics. This generalization enables us to describe quantum system with channel couplings and optical potential in a real time stochastic approach, which seems to give us a new insight into quantum mechanics beyond Copenhagen interpretation.",

note = "Funding Information: able, e.g. coordinate of particle, is described by a definite path determined stochastically. Each sample path has a definite form of trajectory in space-time diagram, while a physical quantity averaged over the ensemble of these sample paths recovers the effect of quantum coherence. This is true even in the Young's double slits interference experiment. Nelson's quantum mechanics gives each definite trajectory and the ensemble of it, but it does not predict which path is selected when one wants to measure the position of a particle. In this sense, this {"}real time stochastic process approach{"} seems to give us a new insight into quantum mechanics beyond Copenhagen interpretation. Recent experimental data of tunneling time using the neutron spin echo shift through the magnetic films \[4\]s eem to agree with the simulation based on our approach \[5\]a nd this study will be reported in near future.
