The quantum tunneling of a singular potential is modeled, as a rule, by the method of regularization. It proceeds from the intermediate usage of a nonsingular-type preimage of the potential function. In this work, it has been ascertained that the preimages continuously differentiable at the point of singularity does not reproduce the singularity in the problem of quantum tunneling.

奇异势垒的量子隧穿正则化

通常，通过正则化方法对奇异电位的量子隧穿进行建模。它从潜在功能的非奇异型原像的中间使用开始。在这项工作中，已经确定在奇异点连续可微化的原像不会在量子隧穿问题中再现奇异点。
