[PRad] [EXTERNAL] Re: new confirmation of X17

  Dear Jennifer and Valery,

 I completely agree with your comments about the authors of this release.
 That is a serious weakness of this new experiment.
 Most likely the reality is that the ATOMKI group just used this new
 facility for the new experiment.

 Still we have to push our experiment as soon as possible.
