We measured the $^{57}$Zn $\beta$-delayed proton ($\beta$p) and $\gamma$ emission at National Superconducting Cyclotron Laboratory. find a half-life of 43.6 $\pm$ 0.2 ms, $\beta$p branching ratio (84.7 1.4)%, identify four transitions corresponding to exotic $\beta$-$\gamma$-$p$ decay mode, second such identification in $f p$-shell. The $p/\gamma$ was used correct for isospin mixing while deter...

We investigate several Pb(n, nγ) and Ge(n, nγ) reactions. We measure γ-ray production from Pb(n, nγ) reactions that can be a significant background for double-beta decay experiments which use lead as a massive inner shield. Particularly worrisome for Ge-based double-beta decay experiments are the 2041-keV and 3062-keV γ rays produced via Pb(n, nγ). The former is very close to the Ge double-beta...

The nature of $J^{\pi}=1^-$ levels $^{96}$Zr below the $\beta$-decay $Q_{\beta}$ value $^{96}$Y has been investigated in high-resolution $\gamma$-ray spectroscopy following $\beta$ decay as well a campaign inelastic photon scattering experiments. Branching ratios extracted from allow absolute $E1$ excitation strength to be determined for populated both reactions. combined data represents compre...

We have studied the core structure of amyloid fibers of yeast prion protein Sup35. We developed procedures to prepare straight fibers of relatively uniform diameters from three kinds of fragments; N (1-123), NMp (1-189), and NM (1-253). X-ray fiber diffraction patterns from dried oriented fibers gave common reflections in all three cases; a sharp meridional reflection at 4.7A, and a diffuse equ...

The radiations from 60-day Sb lN have been studied by several investigators. H ales and Jordan [2] used a 1800 spectrometer to study the beta spectrum of Sb124. Tbey report the presence of two components with maximum cnergies at 0.74 ± O.03 and 2.45 ± 0.07 million electron volts (NIev) . ~1iller and Omtiss [3], u ing a thin magnetic len spectrometer , also ob erved a complex beta specLrum, but ...

The binding of beta-methyl N-acetylglucosaminide (betaMeGlcNAc) to egg-white lysozyme of hen in the tetragonal crystal form was studied by X-ray diffraction techniques to a resolution of 0.25 nm. The binding of the beta-methyl glycoside is almost identical with the binding of beta-N-acetylglucosamine (betaGlcNAc). Real-space refinement of the lysozyme-alpha/beta GlcNAc and lysozyme-betaMeGlcNAc...
