Abstract

We point out a misleading treatment and incorrect expressions in a recent paper published in this Journal [Eur. Phys. J. C (2019) 79: 541] regarding solutions for the Dirac equation in presence of scalar and vector potentials in a class of flat G\"odel-type space-time called Som-Raychaudhuri space-time. Following the appropriate procedure we obtain the solution for this system.
