Abstract
There has been much uncertainty as to the energies of the nuclear-rays of radium D. All the expansion chamber investigations1,2,3,4 showed, in addition to the known secondary β-rays, numerous rays of ranges around 6 mm. in oxygen at S.T.P. and therefore of energies of about 20 kilovolts. These were interpreted by Feather3 and one of us4 (H. O. W. R.) as due to the nuclear electrons.
