NeutrinoInteraction.choose_inelasticity()

Choose an inelasticity for the particle attribute’s shower.

Generates a random inelasticity from an inelasticity distribution based on the interaction type.

Returns

float

Inelasticity (y) value for the interaction.

Notes

The inelasticity calculation is based on Equations 14-18 in the CTW 2011 paper [1].
