Single repeated contact ice charging
Charge transfer in single, repeated collision of ice surfaces. An experimental study of the charging of colliding ice surfaces replicates in part a study (Mason & Dash, 2000, https://doi.org/10.1029/2000JD900104) in which there was qualitative agreement with a prediction of Baker and Dash, (1989...
