Interaction coefficients. The interaction coefficients between a small neutral particle of mass 100 AMU and a small ion of mass 225 AMU interacting with aerosols of diameter d. The interaction between neutral particles, β 00, is given by the blue curve, the interaction between small neutral particles and charged aerosols, β , is given by the red curve. The interaction between a positive or negative ion and neutral aerosols, β ±0, is described with the yellow curve. Finally, the recombination coefficient between two oppositely charged particles is given by the brown curve. The coefficients were calculated assuming Brownian diffusion while including Van der Waals-forces, Coulomb-forces (including image charges) and viscous forces24. Symmetry between positive and negative ions has been assumed, see text
