In a recent comment, Ruth Signorell raises a number of issues that she considers to question the validity of our approach to determine mean free paths for electron scattering in liquid water and our comparison with the results on amorphous ice by Michaud, Wen, and Sanche. Here, we show that these critiques are unjustified, being either unfounded or based on misconceptions by the author of the comment. We nevertheless welcome the opportunity to further clarify certain aspects of our work that we did not discuss in detail in our letter.

The mean free paths of low-energy electrons in liquid water are of fundamental importance for modelling radiation damage and many related physico-chemical processes. Neither theoretical predictions nor experimental estimations have so far converged t
o yield reliable values for these parameters. We therefore introduce a new approach to determine the elastic and inelastic mean free paths (EMFP, IMFP) based on experimental data. We report extensive ab-initio calculations of electron quantum scattering with water clusters, which are brought to convergence with respect to the cluster size. This provides a first-principles approach to condensed-phase scattering that includes both multiple-scattering and condensation effects. The obtained differential cross sections are used in a detailed Monte-Carlo simulation to extract EMFP and IMFP from two recent liquid-microjet experiments that determined the effective attenuation length (EAL) and the photoelectron angular distribution (PAD) following oxygen 1s-ionization of liquid water. For electron kinetic energies from 10 eV to 300 eV, we find that the IMFP is noticeably larger than the EAL. The EMFP is longer than that of gas-phase water and the IMFP is longer compared to the latest theoretical estimations, but both the EMFP and IMFP are much shorter than suggested by experimental results for amorphous ice. The Python module developed for the analysis is available at https://gitlab.com/axelschild/CLstunfti and can be used to further refine our results when new experimental data become available.
This is a reply to the comment from E. Amselem et al. on our paper (Phys. Rev. Lett. 109, 150401 (2012), arXiv:1207.0059).
In this short note we reply to a comment by Callegaro et al. [1] (arXiv:2009.11709) that points out some weakness of the model of indeterministic physics that we proposed in Ref. [2] (Physical Review A, 100(6), p.062107), based on what we named finit
e information quantities (FIQs). While we acknowledge the merit of their criticism, we maintain that it applies only to a concrete example that we discussed in [2], whereas the main concept of FIQ remains valid and suitable for describing indeterministic physical models. We hint at a more sophisticated way to define FIQs which, taking inspiration from intuitionistic mathematics, would allow to overcome the criticisms in [1].
In this Reply, we respond to the above Comment. Our computation [Phys. Rev. D 91 (2015) 074512] only took into account pure QCD effects, arising from quark mass differences, so it is not surprising that there are discrepancies in isospin splittings a
nd in the Sigma - Lambda mixing angle. We expect that these discrepancies will be smaller in a full calculation incorporating QED effects.
The Authors reply to the Comment of Golub and Lamoreaux. The experimental limit on the neutron electric dipole moment remains unchanged from that previously announced.
