Robust techniques for polarization and detection of nuclear spin ensembles [PDF]
Phys. Rev. B 96, 174436 (2017), 2017 Highly sensitive nuclear spin detection is crucial in many scientific areas including nuclear magnetic resonance spectroscopy (NMR), imaging (MRI) and quantum computing. The tiny thermal nuclear spin polarization represents a major obstacle towards this goal which may be overcome by Dynamic Nuclear Spin Polarization (DNP) methods. The latter often rely

A Review of the Uses of Nuclear Radiation in Tobacco and Smoke Research
Contributions to Tobacco and Nicotine Research, 1990 In summary, nuclear radiation has been widely used to elucidate many aspects of the mechanisms of tobacco being converted to smoke. In addition, the mechanisms of smoke transfer, tobacco inorganic chemistry and smoke filtration have been clarified by ...

Nuclear Structure Studies of Neutron-Rich Nuclei : Astrophysical Implications [PDF]
, 2017 It is proposed here to investigate three major properties of the nuclear force that influence the amplitude of shell gaps, the nuclear binding energies as well as the nuclear $\beta$-decay properties far from stability, that are all key ingredients for modeling the r-process nucleosynthesis.

$γ$-ray Angular Distributions in Single Nucleon Transfer Reactions with Exotic Strontium Isotopes [PDF]
arXiv, 2023 $\gamma$-ray angular distributions help assign spin and parity to excited energy levels in nuclei. The spectroscopy of $^{94,96}$Sr studied through the single neutron transfer reactions with $^{95}$Sr beam in inverse kinematics [$^{95}$Sr(d,p)$^{96}$Sr; $^{95}$Sr(d,t)$^{94}$Sr] revealed a rich nuclear structure with many excited states.

Determination of photo-nuclear cross section of $^{61}$Ni($γ$,xp) reaction via surrogate ratio technique [PDF]
arXiv, 2022 The photo nuclear reaction cross section of $^{61}$Ni($\gamma$,xp) reaction have been measured by employing surrogate reaction technique. This indirect method is used for the first time to obtain the cross section of photo nuclear reaction. The compound nucleus $^{61}$Ni$^{*}$ was populated using the transfer reaction $^{59}$Co($^{6}$Li,$\alpha$) at E ...

Extraction of two-photon contributions to the proton form factors [PDF]
Phys.Rev. C71 (2005) 015202, 2004 Significant discrepancies have been observed between proton form factors as measured by Rosenbluth separation and polarization transfer techniques. There are indications that this difference may be caused by corrections to the one photon exchange approximation that are not taken into account in standard radiative correction procedures.
