Phys. Rev. A 66, 044101 (2002) [3 pages]Time of occurrence observable in quantum mechanicsReceived 20 March 2002; published 4 October 2002 We propose a general construction of an observable measuring the time of occurrence of an effect in quantum theory. Time delay in potential scattering theory is computed as a straightforward application. © 2002 The American Physical Society URL:
