Compute the wavefunction and the probability to tunnel for, Ask an Expert

Academics

Compute the wavefunction and the probability to tunnel, for a proton in the potential: V(x)=0, when x< -0.20 nm, and x>0.00 nm, and V(x)=2.0*10-19 J otherwise.
Consider this wavefunction to have a total energy of 1.2 eV, and its functional form in the x>0.00 region to be psi(x)=exp(i*k*x)
