矩阵势的电流坐标因式分解与能级配对
Factorization Method in Curvilinear Coordinates and Pairing of Levels for Matrix Potentials
摘要：
在任意曲线坐标系下建立了多维分解方法。极坐标和球坐标的特殊情况下，被认为是与分离变量的矩阵势构造。得到了一类新的矩阵势，它揭示了能级的双重简并或等距分裂（隐对称性）。
英文摘要：
Multidimensional factorization method is formulated in arbitrary curvilinear coordinates. Particular cases of polar and spherical coordinates are considered and matrix potentials with separating variables are constructed. A new class of matrix potentials is obtained which reveals a double degeneracy or equidistant splitting of energy levels (hidden symmetry).
