Here, we present room temperature neutron structures of human MnSOD at physiological pH in Mn3+and Mn2+states and reveal how the atomic locations of all protons in the enzyme active site change when the active site metal goes through a redox cycle. Direct experimental evidence is provided for ...
Full size table Fig. 5 Impact of the initial target nucleus on the yields along different hyperisotopic chains. The neutron-deficient 124Xe favors the production of lighter and more neutron-deficient isotopes in the ΛMo and ΛPd chains, while 132Xe provides high yields in neutron-rich and he...

The region of the nuclear chart below the heaviest self-conjugate doubly-magic nucleus,100Sn, is a continuing subject for intense theoretical and experimental studies. The closely equal number of protons and neutrons (N = Z) in the regions atomic nuclei leads to enhanced neutron-proton pairi...

The neutron irradiated samples which were cut from the non-deformed heads of the ir- radiated CERT samples, are in the shape of 10 mm ¯at tensile samples with a gauge length of 3 ´ 2.5 ´ 0.3 mm3. The size was optimised to ®t the geometry of the as-re-...
2 Baryon decay: experimental status and prospects The current lower limits on the lifetimes for many pos- sible proton and neutron decay modes provided by the Super-Kamiokande experiment are summarized in Refs. [4,8,47,48]. As we review below, proton decay in the min- imal supersymmetric ...
(Fig.4, inset). The ash abundances of Urca nuclides are particularly notable49,50, which may impact the interpretation of model–observation comparisons for X-ray superbursts and neutron-star crust cooling51,52, as well as of important electron-capture heating sources53. Of these, we note ...
