一类具有形状不变性的新可解势

A New Solvable Potential with Shape Invariance

利用超对称量子力学中的因子分解法得到了一类特殊的形状不变势，它包括Ｅｃｋａｒｔ势作为其一个子类．该势在超对称变换下失去一个参数，但仍然能够精确求出其能量本征值和本征函数．

sing the method of factorization,a new solvable potential is generated from the Eckart po-tential.The new potential possesses unusual shape invariance. It is exactly solvable,but Ioses afree parameter in the supersymmetric transformation.
