The branching ratios of the electron-capture transitions in the decay of 7 Be and 65 Zn were measured to be 0.1042 ± 0.0018 and 0.493 ± 0.0008 at the 68 per cent confidence level, respectively. They were obtained by measuring the neutron yields fro

Measurements of σf(238U)σf(235U) were primarily carried out in the “plateau”-range at 2·5 MeV. Gas scintillation counters and the time-of-flight technique were used. Four different methods were employed for mass assignment. The measured values

The capture cross-section shape of gold has been measured in the energy range 25–500 keV and normalized at 30 keV using a ‘best fit’-value. The shape measurement was performed using a large liquid scintillator as a capture γ-ray detector and b
