Abstract

RANGEFia. 2. Feather plot for Ca&, I.O 12,000 counts per minute, and the contribution due to gamma-rays and other unabsorbed contaminants was less than one part in 3000 with the strongest source, thus indicating the absence of any appreciable amount of gamma-radiation.The absorption curve obtained with the strongest source is shown in Fig. 1.The Feather plot, shown in Fig. 2, gives a range of 64+1 mg/cm'.Glendenin' has shown that a reliable range-energy curve for the low energy region can be derived from the data of Marshall and %'ard' for monoenergetic electrons and beta- ray spectrograph data on low energy beta-emitters.Glen- denin's curve is identical with that of Marshall and Nard below 0.5 Mev.Using this range-energy curve, we have found that the Ca~beta-radiation has a maximum energy of 260+5 kev.%'e have found no evidence of any harder beta-radiation, or of any gamma-radiation at all in the course of this investigation.'Ackeomledgesents.-This work has been

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
