Broadband Relaxation-Optimized Polarization Transfer in Magnetic Resonance [PDF]

open access: yes, 2004
Many applications of magnetic resonance are limited by rapid loss of spin coherence caused by large transverse relaxation rates. In nuclear magnetic resonance (NMR) of large proteins, increased relaxation losses lead to poor sensitivity of experiments ...

Theoretical applications to nuclear astrophysics [PDF]

open access: yesEPJ Web of Conferences
Nuclear reaction study is important to understand elemental abundance in the universe and stability of stars. For several reactions due to the paucity of experimental data or diffculties in performing the direct measurements, we depend upon theoretical ...

Recent direct reaction experimental studies with radioactive tin beams [PDF]

open access: yes, 2014
Direct reaction techniques are powerful tools to study the single-particle nature of nuclei. Performing direct reactions on short-lived nuclei requires radioactive ion beams produced either via fragmentation or the Isotope Separation OnLine (ISOL) method.

Preparation of Nuclear Spin Singlet States Using Spin-Lock Induced Crossing [PDF]

open access: yes, 2013
We introduce a broadly applicable technique to create nuclear spin singlet states in organic molecules and other many-atom systems. We employ a novel pulse sequence to produce a spin-lock induced crossing (SLIC) of the spin singlet and triplet energy ...

Dynamic Nuclear Polarization and Other Magnetic Ideas at EPFL

open access: yesCHIMIA, 2012
Although nuclear magnetic resonance (NMR) can provide a wealth of information, it often suffers from a lack of sensitivity. Dynamic Nuclear Polarization (DNP) provides a way to increase the polarization and hence the signal intensities in NMR ...

Developing new methods to investigate nuclear physics input to the cosmological lithium problem

open access: yesEPJ Web of Conferences, 2013
A significant challenge to nuclear astrophysics is the cosmological lithium problem, where models of Big Bang nucleosynthesis indicate abundances of 7Li two to four times larger than what is inferred via spectroscopic measurements of metal-poor stars ...
