We have measured the transverse asymmetry AT' in 3He (e,e') quasielastic scattering in Hall A at Jefferson Laboratory with high precision for Q2 values from 0.1 to 0.6(GeV/c)2. The neutron magnetic form factor GnM was extracted based on Faddeev calculations for Q2=0.1 and 0.2(GeV/c)2 with an experimental uncertainty of less than 2%.

Precise, Highly Female-Biased Sex Ratios In A Social Spider, Leticia Avilés, John Mccormack, Asher Cutter, Todd Bukowski

It has been recognized for some time that the risk of producing maleless clutches should select for a lower than binomial variance in the sex ratio of organisms with female–biased sex ratios, small clutches and breeding groups containing the clutch of a single female. However, to date, precise sex ratios have only been reported for organisms with haplodiploid sex determination, a system which allows direct control of the sex of individual offspring. In contrast, under heterogametic sex determination chance is expected to play a crucial role in determining the sex composition of any one family, in particular when males are …

The ratio of the proton's elastic electromagnetic form factors, G Ep / G Mp, was obtained by measuring Pt and Pl, the transverse and the longitudinal recoil proton polarization, respectively. For elastic ep→ep, G Ep / G Mp is proportional to Pt / Pl. Simultaneous measurement of Pt and Pl in a polarimeter provides good control of the systematic uncertainty. The results for the ratio G Ep / G Mp show a systematic decrease as Q2 increases from 0.5 to 3.5GeV2, indicating for the first time a definite difference in the spatial distribution of charge …
