Here also is the Simmel et al. 2002 paper which parameterises the Long Kernel: https://www.sciencedirect.com/science/article/pii/S0169809501001314 (equations 11-14)

and here is CLEO's implementation of it: https://github.com/yoctoyotta1024/CLEO/blob/13e57f71b433c71493ad41a62c92073cd0e69f92/libs/superdrops/collisions/longhydroprob.cpp#L30

(+ terminal velocity here: https://github.com/yoctoyotta1024/CLEO/blob/13e57f71b433c71493ad41a62c92073cd0e69f92/libs/superdrops/terminalvelocity.cpp#L58)
