Abstract
We study the ionization and light yields produced by nuclear recoils at low energies in pure crystals and noble liquids in the context of Lindhard’s integral equation, incorpo- rating the effects of binding energy, improved modeling of the electronic stopping, and electronic straggling. We consider three different models for the electronic stopping power that incorporate Coulomb repulsion effects at low energies, and Bohr electronic stripping for high energies. Finally, we discuss possible new effects near threshold.

Strengths
Detailed study with possible new effects about the ionization and light yields produced by nuclear recoils at low energies in crystals and noble liquids. Authors consider three different models for the electronic stopping power taking to account more effects. The work is done in the frame of EXCESS workshop which was triggered by recent unexplained rise of events at low energies.
Weaknesses
typos and inconsistency in writing, requires careful formatting
Report
The manuscript meets criteria. I recommend to publish it after some corrections.
Requested changes
- in introduction you say "pure crystals" - be more specific what do you mean
-" by the an ion" the or an?
- takes in to account -> into
- formula (2) please explain variables for clarity
- in introduction you state that Lindhard equation describes data for Si below 4keV accurately, later you state that it fails. Can you make it more clear?
- "most of then"? or them?
- CM frame?
- "Low and high energy effects for Se"? Se - write with words
- the main facts ignored?
- we are going to consider?
- give numbers to all formulas
