Thus, () ( ) 38 1 39 2 2 1.2 10 m 30m 7.2 10 bL = × . One can see that 2 bL Te is very small (essentially zero). 80. The kinetic energy of the car of mass m moving at speed v is given by Em v = 1 2 2 , while the potential barrier it has to tunnel through is U b = mgh , where h = 24 m. According to Eq. 38-21 and 38-22 the tunneling probability is given by
