// File: POSITRONIUM.ratdb // Brief: Values for the simulation of the effects of Ortho-Positronium (o-Ps). // There are only rough values for one material type, taken from literature: // - LAB + 2g/L PPO + 5% surfactant + Te + water. // - These values are also not greatly affected by Te concentration. // - Therefore these are expected to work for any material with roughly LAB + 2g/L PPO + extras. // - Other materials are unknown, but are assumed to be closer to this than to no o-Ps at all. // => Therefore only one table is used for all materials so far. // See docDB for more details on the meaning and origin of the values defined below: doc-7593. // // Date: 2022-09-21 // Author: James Page (jp643@sussex.ac.uk) // // REVISION HISTORY: // { type: "POSITRONIUM", index: "", // Default (LAB + 2g/L PPO + extras) version: 1, pass: 0, run_range: [0, 0], comment: "", timestamp: "", formfrac: 0.36, // o-Ps formation fraction (in all e+e- annihilations) lifetime: 2.7, // o-Ps lifetime (ns) random: true // get o-Ps lifetime from random (exp decay) distribution?
