On the universal scattering time of neutrons

Abstract

The tunneling and barrier interaction times of neutrons have been previously measured. Here we show that the neutron interaction time with barriers corresponds to the universal tunneling time of wave mechanics, which was formerly observed with elastic, electromagnetic, and electron waves. The universal tunneling time seems to also hold for neutrons. Such an adequate general wave mechanical behavior was conjectured by Brillouin. Remarkably, wave mechanical effects and even virtual particles hold from the microcosmos up to the macrocosmos.
