Hydrogen atom in momentum space with a minimal length

Abstract

A momentum representation treatment of the hydrogen atom problem with a generalized uncertainty relation,which leads to a minimal length ({\Delta}X_{i})_{min}= \hbar \sqrt(3{\beta}+{\beta}'), is presented. We show that the distance squared operator can be factorized in the case {\beta}'=2{\beta}. We analytically solve the s-wave bound-state equation. The leading correction to the energy spectrum caused by the minimal length depends on \sqrt{\beta}. An upper bound for the minimal length is found to be about 10^{-9} fm.
