Question

In one model system, this phenomenon's probability equals the reciprocal of one plus a term proportional to sinh ("sinch") squared of k-sub-one a. The log-probability of this phenomenon (read slowly) equals negative two times the integral of the square root of two-m-over-h-bar-squared times V minus E over the interval between two turning points in the (20[4]0[2])WKB (20[1])approximation. Stellar nucleosynthesis (20[1]0[1])is (0[1])possible because (20[1])this (20[2])phenomenon overcomes (10[2]0[2])the (10[2]0[3])(*) Coulomb barrier, (0[2])which (0[1])also determines (0[1])the rate of this process (0[1])in (10[1]0[1])George Gamow's (0[1])("GAM-off's") model of alpha decay. (10[2])This phenomenon (0[1])allows low-energy particles to escape (10[1])a (10[1])finite (10[1])square well. For (0[1])10 points, (10[1])a particle (10[1])passes through (10[1])a (10[1])potential barrier in what (10[1])quantum (10[2])mechanical (10[13]0[2])phenomenon? ■END■
