An investigation has been made to determine the effect which the Coulomb interaction energy between an ion and the background plasma has on the Urca process in dense stellar interiors. It was found that the change in interaction energy which occurs when an ion changes its charge by one unit can increase significantly the threshold for electron capture. The exact threshold depends on the particular ionic configuration which exists at the time the beta-interaction occurs. There thus exists a distribution of possible thresholds about some mean value. Monte Carlo techniques were used to investigate this distribution. The effect on the energy generation rate of the Urca process was found to be small. The thermal effects of the Urca process are discussed, and calculations are presented which indicate several interesting properties of the convective Urca process.
