    "abstract": "In this paper we report on our theoretical studies of various aspects of the\ncorrelated stopping power of two point-like ions (a dicluster) moving in close\nbut variable vicinity of each other in some metallic target materials the\nlatter being modelled by a degenerate electron gas with appropriate densities.\nWithin the linear response theory we have made a comprehensive investigation of\ncorrelated stopping power, vicinage function and related quantities for a\ndiproton cluster in two metallic targets, aluminum and copper, and present\ndetailed and comparative results for three approximations to the electron gas\ndielectric function, namely the plasmon-pole approximation without and with\ndispersion as well as with the random phase approximation. The results are also\ncompared, wherever applicable, with those for an individual projectile.",
