BOHR, Niels. "Scattering and Stopping Fission Fragments", in Physical Review, volume 58, number 7, October 1, 1940, pp 654-656, in the issue of pp 583-663. In the original wrappers. A very good copy. $250
Evidently Bohr did not have time to address these issues in 1930's though did so with three papers (this being one of them) in 1940. See: The Penetration of Charged Particles Through Matter (1912 - 1954), edited by J. Thorsen.
