Unformatted text preview: h r s . The transmission probability, P T , is defined by P T = 1 P R = 0 . Note that since no particles are created or destroyed P R + P T = 1 . Probability Density: The probability density is given by + − + − + = Ψ = ) 2 sin( 1 2 ) 2 cos( 1 ) 1 ( 2 2    ) , (  ) ( 2 2 2 2 2 kx r r kx r r A t x x L L L ρ krx L R R e r A t x x 2 2 2 2 1 4    ) , (  ) ( − + = Ψ = , where 2 2 h mE k = and 1 − = E V r and κ = kr . Step Potential: V > E8642 2 x Probability Density Interference minimum! NonZero probability to be in the “classically forbidden” region!...
