Levels in the N = 82 nucleus 139La populated in 139Ba decay
(Elsevier, 1968-10-21)
The decay of 139Ba to levels in 139La was investigated using Ge(Li) gamma-ray detectors. On the basis of energy, intensity and coincidence measurements, a new decay scheme is proposed. In addition to well-known levels at ...
Decay of Se81m and Se81
(Elsevier, 1962)
The gamma rays in Se81 and Br81 following the decay of Se81m and Se81 were studied with a magnetic spectrograph. Three internal conversion lines were observed in these measurements. Gamma-ray spectra taken with a NaI(Tl) ...
The decay of 75Se
(Elsevier, 1969-06-16)
The gamma-ray spectrum associated with the electron capture decay of 75Se has been studied with Ge(Li) spectrometers. Coincidence spectra were taken with a Ge(Li)---Ge(Li) combination. The data do not support a recent ...
The decay of 159Gd
(Elsevier, 1968-04-12)
Precision energy measurements on four gamma rays in the 159Gd --> 159Tb decay were performed with a 2 m curved-crystal spectrometer. Energies of the other gamma rays and all gamma intensities were determined with a ...
The decay of 140La to levels in 140Ce
(Elsevier, 1968-05-24)
The decay of 140La to levels in 140Ce has been studied with Ge(Li) spectrometers and [gamma]-[gamma] coincidence techniques. Precision energy and intensity values for 25 [gamma]-rays are reported. These transitions have ...
The application of thin-plate spark chambers to high-energy [pi]-p experiments

Decay of Re188
(Elsevier, 1960)
The gamma rays in Os188 following beta decay of 18-h Re188 have been studied using coincidence and directional correlation techniques. The results agree with the principal features of the decay scheme proposed by Johns et ...
A new method of angular correlation measurements
(Elsevier, 1969-11-15)
A new type of angular correlation apparatus is described, and a mathematical model of its statistics is given. The angular correlation of coincident nuclear radiations can be measured by detecting intensity correlations ...
Interference between resonances in a slab lattice
(Elsevier, 1968-03)
In calculating resonance absorption for one resonance, the effect of neighbouring resonances is usually neglected. It is, therefore, customary to assume that the slowing-down flux takes its asymptotic value above the ...
