Phys. Rev. Lett. 74, 2405–2409 (1995)How Much Time Does a Tunneling Particle Spend in the Barrier Region?Received 9 June 1994; published in the issue dated 27 March 1995 The question in the title may be answered by considering the outcome of a “weak measurement” in the sense of Aharonov, Albert, and Vaidman. Various properties of the resulting time are discussed, including its close relation to the Larmor times. It is a universal description of a broad class of measurement interactions, and its physical implications are unambiguous. © 1995 The American Physical Society URL:
