Smythe, Henry D[eWolf] [sic], AEC, from R.R.W., re supplement to article describing compact 600 Mev synchrotron, correction to original article: energy W in formula by Levinger for number of neutrons per photon absorbed should have been in units of 100 Mev, still believes gamma--rays more useful than neutrons [cc]; reply, 9/13/1952 [tls], 8/21/1952
