    "abstract": "We discuss a possible approach to the absorption problem in Quantum Mechanics\nbased on using of singular attractive potentials in the corresponding\nSchr\\\"{o}dinger equations. Possible criteria for selection of exact solutions\nof these equations are considered and it is shown that different models of\nabsorption can be realized by a special choice of exact solutions. As an\nexample, the motion of charged particles in the Aharonov-Bohm (AB) and the\nscalar attractive $\\rho^{-2}$ potentials is investigated in detail. Other\nattractive potentials are briefly considered.",
