An Elementary Model of Dynamical Tunneling

摘要: Abstract In the scattering of a quantum particle by potential V(x) := (1 + x 2 ) -1 , we derive bounds on amplitudes for energies E greater than top bump. The are form cte exp –ħ s ( k ′), where s(k, k′ is classical action relevant instanton energy shell = . method designed to suit as much possible n -dimensional case but applied here only 1.
