Direct Mass Measurements of Neutron-Rich Zinc and Gallium Isotopes: An Investigation of the Formation of the First r-Process Peak.

The prediction of isotopic abundances resulting from the rapid neutron capture process (r process) requires high-precision mass measurements. Using TITAN's on-line time-of-flight spectrometer, first time mass measurements are performed for ^{83}Zn and ^{86}Ga. These measurements reduced uncertainties, and are used to calculate isotopic abundances near the first r-process abundance peak using astrophysical conditions present during a binary neutron star (BNS) merger.

Sex, religion, and the single woman c.1950-75: the importance of a 'short' sexual revolution to the English religious crisis of the sixties.

The English 'sexual revolution' has recently become increasingly conceived as 'long', lasting many decades, and by some historians as a gradual phenomenon, but reaching a peak with the introduction of the oral contraceptive pill in the 1960s. At the same time, the 'religious crisis' of the same decade has been attributed by some recent scholarship to liberal Christian revolt within the churches, and largely unconnected with sex. This article offers different views.
