title: The efficiency curve: a new function.
abstract: Working from first principles, an efficiency curve function has been developed by considering the physics of photon transport through matter. The function has been compared to other function in popular usage and been found to fit the data better especially about the knee of the curve. The main disadvantage of the new function is that it is data hungry, but this can be overcome by use of Monte Carlo simulations.
