Comment on "Surface roughness effect on ultracold neutron interaction with a wall and implications for computer simulations" A. Steyerl et.al., arxiv: 0911.4115v1 [1]

TL;DR

This paper refutes previous claims of systematic errors in neutron lifetime measurements, arguing that the simulation and assumptions in the critique are flawed and do not accurately represent the original experiment.

Contribution

It clarifies misunderstandings about the experimental methods and demonstrates that the critique's simulation is inadequate and unreliable.

Findings

The critique's assumptions are based on misreading the original work.

The simulation in the critique does not match experimental results.

No valid conclusions can be drawn from the flawed simulation.

Abstract

In above mentioned article [1] assumptions of possible systematic errors of our experiment on measuring of the neutron lifetime [2] have been made. In the given comment we are obliged to explain, that assumptions made in [1] are erroneous. They are caused by an inattentive reading of our work [2] and by the improper understanding the methods used in our work [2]. Simulation of experiment [2] carried out in [1] seems to be imperfect and doesn't describe the experimental results. Therefore it is impossible to do any conclusions from such simulation.
