Abstract

We develop a Green's function formalism and with it we are able to obtain close expressions for the tunnelling and for the reflection times. For eachproblem, there appear two characteristic times which correspond to the real and imaginary parts of the integral of the Green's function at coincidingcoordinates. The time related to the imaginary part represents the minimumuncertainty of the measurement. A strong analogy between the results of the different existing approaches is established. and we show that their maindifferences are due to finite-size effects.
