Say I have a particle with a kinetic energy of 5 (in some units). And I have a potential barrier of 10 between 0<x<1 (again, in ome unit system), and 0 elsewhere. According to quantum theory, the partcile may be found between 0 and 1. And in this region, if the energy is conserved (5 = T + 10), shouldn't the kinetic energy be -5?!? So that [tex]\hat T \psi_2 = -5 \psi_2[/tex].(adsbygoogle = window.adsbygoogle || []).push({});

What's going on here??
