关于双原子分子共振的Born-Oppenheimer近似

On the Born-Oppenheimer approximation of diatomic molecular resonances

André Martinez, Vania Sordoni

摘要:

本文给出了一般双原子分子哈密顿量的一种新的约化,在核碰撞集附近不作任何修改。由此产生的有效哈密顿量是一个光滑的半经典伪微分算子(半经典参数是核质量的平方根的倒数)和一个半有界算子的总和,该算子局限于对应于核碰撞集的椭圆区域。我们还研究了它的指数权重的行为,并给出了几个应用程序的分子共振出现,可以很好地定位。

英文摘要:

We give a new reduction of a general diatomic molecular Hamiltonian, without modifying it near the collision set of nuclei. The resulting effective Hamiltonian is the sum of a smooth semiclassical pseudodifferential operator (the semiclassical parameter being the inverse of the square-root of the nuclear mass), and a semibounded operator localised in the elliptic region corresponding to the nuclear collision set. We also study its behaviour on exponential weights, and give several applications where molecular resonances appear and can be well located.
