This paper presents the dynamical properties of a Rydberg hydrogen atom between two metal surfaces using phase space analysis methods.The dynamical behaviour of the excited hydrogen atom depends sensitively on the atom-surface distance d.There exists a critical atom-surface distance d c = 1586 a.u.When the atom-surface distance d is larger than the critical distance d c,the image charge potential is less important than the Coulomb potential,the system is near-integrable and the electron motion is regular.As the distance d decreases,the system will tend to be non-integrable and unstable,and the electron might be captured by the metal surfaces.更多还原
This paper presents the dynamical properties of a Rydberg hydrogen atom between two metal surfaces using phase space analysis methods. The dynamical behaviour of the excited hydrogen atom depends sensitively on the atom-surface distance d. There exists a critical atom-surface distance dc = 1586 a.u. When the atom-surface distance d is larger than the critical distance de, the image charge potential is less important than the Coulomb potential, the system is near-integrable and the electron motion is regular. As the distance d decreases, the system will tend to be non-integrable and unstable, and the electron might be captured by the metal surfaces.
