激发态奇异原子的散射过程:紧耦合方法

Scattering Processes of Excited Exotic Atoms: Close-Coupling Approach

V. P. Popov, V. N. Pomerantsev

摘要:

采用密耦合方法研究了处于激发态的奇异原子与氢原子的弹性散射、Stark跃迁和库仑退激等散射过程。考虑了真空极化和$ns$ -态(强子原子)的强相互作用位移。计算上述过程的微分和积分截面,以将其用作级联计算的输入。研究了封闭通道对散射过程的影响。

英文摘要:

The scattering processes of exotic atoms in excited states from hydrogen such as elastic scattering, Stark transitions and Coulomb de-excitation are studied within a close coupling approach. The vacuum polarization and the strong interaction shifts of $ns$-states (in case of hadronic atoms) are taken into account. The differential and integral cross sections of the above processes are calculated to use them as the input in cascade calculations. The effect of closed channels on the scattering processes is investigated.
