  Discrete mathematics, the study of finite structures, is one of the fastest
growing areas in mathematics and optimization. Discrete fractional calculus
(DFC) theory that is an important subject of the fractional calculus includes
the difference of fractional order. In present paper, we mention the radial
Schr{\"o}dinger equation which is a physical and singular differential
equation. And, we can obtain the particular solutions of this equation by
applying nabla ($ \nabla $) discrete fractional operator. This operator gives
successful results for the singular equations, and solutions have fractional
forms including discrete shift operator $ E $.
