G factor of the 59/2 - isomer in Gd147

The g factor of the 10 995 keV, Je=(59/2-, and T1/2=0.8 ns level in Gd147 has been determined by the transient field method for ions recoiling through a magnetized Gd foil at a temperature of 100 K. The Ge76(76Ge,5n)147Gd reaction at E(76Ge)=310 MeV was used to provide high recoil velocity. A 100 ps flight time in vacuum between the target and the ferromagnet of 100 ps ensured that the -ray cascades fed the (59/2 level before the recoil ions traversed the Gd foil. The g factor was extracted from standard double ratios with the known parametrization of the transient field, yielding g=0.38(7). This value is in agreement with the predicted wave function and experimental single-particle moments in this mass region. Results for levels in 146,148Gd were also obtained

Novel genetic loci associated with hippocampal volume

The hippocampal formation is a brain structure integrally involved in episodic memory, spatial navigation, cognition and stress responsiveness. Structural abnormalities in hippocampal volume and shape are found in several common neuropsychiatric disorders. To identify the genetic underpinnings of hippocampal structure here we perform a genome-wide association study (GWAS) of 33,536 individuals and discover six independent loci significantly associated with hippocampal volume, four of them novel. Of the novel loci, three lie within genes (ASTN2, DPP4 and MAST4) and one is found 200 kb upstream of SHH. A hippocampal subfield analysis shows that a locus within the MSRB3 gene shows evidence of a localized effect along the dentate gyrus, subiculum, CA1 and fissure. Further, we show that genetic variants associated with decreased hippocampal volume are also associated with increased risk for Alzheimer's disease (rg =-0.155). Our findings suggest novel biological pathways through which human genetic variation influences hippocampal volume and risk for neuropsychiatric illness
