In this report, electric quadrupole corrections to the two neutron removal cross section measured in heavy ion collisions are estimated for Au and Co targets. The quadrupole process is assumed to proceed primarily through excitation of the giant isovector quadrupole resonance, which then decays by neutron emission. For Co, the contribution from E2 radiation is found to be small, while for Au we...

background: so far, non-invasive diagnostic approaches such as ultrasound, magnetic resonance imaging, or blood tests do not have sufficient diagnostic power for endometriosis disease. lack of a non-invasive diagnostic test contributes to the long delay between onset of symptoms and diagnosis of endometriosis. objective: the present study focuses on the identification of predictive biomarkers i...

We report new solid-state 127I NMR results for sheelite periodates, MIO4 (M = Na+, K+, Rb+, and NH4+), and for pseudo-scheelite CsIO4 and HIO4. The observed 127I quadrupole coupling constants were between 1.0 and 43.0 MHz in agreement with previous NQR data. In contrast to an early 127I NMR study (S. L. Segel and H. M. Vyas, 1980, J. Chem. Phys. 72, 1406), we found that the 127I chemical shift ...

The nuclear magnetic resonance of Zn in hexagonal close-packed Zn metal has been observed at 4.2 K by pulsed NMR with three different frequencies. The spin echo profile showed a well resolved powder pattern due to electric quadrupole interaction. The quadrupole coupling constant was determined to be e q Q/h = 12.0 (4) MHz. The spinspin and spin-lattice-relaxation times were measured to be T2 = ...
