研究人员运用绝热不变量方法以及Born-Oppenheimer近似成功地计算了一对耦合振子在所谓的"半量子混沌"状态下的基态波函数,从而得......

We employ a recently amended Born-Oppenheimer (hereafter shortly BO) approximation <a href="#1">[1]</a> to treat inelast......

Two-electron atoms have been investigated near threshold of double escape within the framework of hyperspherical coordin......

We present an improved Born-Oppenheimer method for the treatment of molecules. Our development is based on taking into a......
