The PAPERS-TO-OBTAIN text gives the second paper without authors; Crossref confirms it is Okuto and Crowell. The folder already holds a screenshot of the 1972 abstract (gov-Misc/Energy-Conservation-Impact-Ionization.png).
Bearing on claims
Peripheral to the Moray claims: these papers concern avalanche (impact) ionisation in Ge, Si, GaAs and GaP and show that measured ionisation coefficients respect energy conservation (the 1972 abstract says some Si data "do not appear to be consistent with energy conservation", i.e. the data were in error). They bear on the semiconductor-cascade hypothesis put to the review for Claim 4, not on any measured Moray result.
