An examination of British and French weights exchanged between the Royal Society and the Academie royale des sciences in the 1730s has led to a re‐assessment of the Elizabethan troy standards from the Exchequer and the suggestion that the mass of t

The decay of 237Np has been investigated from singles and coincidence γ-ray spectra acquired using Ge(Li) detectors. Forty-two γ rays have been observed and all but one have been placed in the level scheme of 233Pa. The presence of unobserved trans

The decay of 233U was examined using Ge(Li) and Si(Li) gamma ray spectrometers in singles and coincidence configurations. Chemical separation of the contaminating daughter products was effected through anion exchange. Of the 117 gamma rays observed h

Previous work on the decay of 211Pb has been developed and extended using lithium-drifted germanium detectors and sum–coincidence techniques. A more detailed level scheme for 211Bi has been produced with greater precision in the determination of th

Magnetic spectrometer studies have revealed that the β decay of Cs134 proceeds via three partial spectra whose end-point energies, intensities, and log10ft values are as follows:[Formula: see text]No evidence is found for β transitions of intermedi

In the decay of neptunium-239 only two γ-rays with energies in excess of 335 kev have been detected. These have energies of 440 ± 10 and 490 ± 10 kev and intensities of 3.6 ± 0.9 × 10−5 and 2.0 ± 0.5 × 10−5 photons per disintegration respe

Concentrations of radon, thoron, and particulate fallout have been evaluated on a day-to-day basis from December 1958 to May 1962. The results are given in detail for the period linking the International Geophysical Year (I.G.Y.) to the program of th

The design and operation of Rosenblum-type spark counters having plane, concave and convex cathodes is described, and discussed with reference to the counting characteristics, useful life and background counting rate. The absolute efficiency of the c

SynopsisThe shape factors of the partial β-spectra of highest end-point energy in the decay of 72Ga and 140La have been calculated and compared with the only previously reported determination of these quantities. For both isotopes the shape factor i
