Is there a readable link? <a href="https://archive.ph/FIycK" rel="nofollow">https://archive.ph/FIycK</a> doesn't work.
There's a different article on the same topic which isn't paywalled at <a href="https://physics.aps.org/articles/v17/161" rel="nofollow">https://physics.aps.org/articles/v17/161</a> . It also provides links at the bottom to the papers being discussed.
