Title: Measurement of the doubly-polarized $\vec{{}^{3}{He}} (\vec{γ}, n) p p$ reaction at 16.5 MeV and its implications for the GDH sum rule

Abstract

We report new measurements of the double-polarized photodisintegration of 3He at an incident photon energy of 16.5 MeV, carried out at the High Intensity γ-ray Source (HIγS) facility located at Triangle Universities Nuclear Laboratory (TUNL). The spin-dependent double-differential cross sections and the contribution from the three-body channel to the Gerasimov–Drell–Hearn (GDH) integrand were extracted and compared with the state-of-the-art three-body calculations. The calculations, which include the Coulomb interaction and are in good agreement with the results of previous measurements at 12.8 and 14.7 MeV, deviate from the new cross section results at 16.5 MeV. The GDH integrand was found to be about one standard deviation larger than the maximum value predicted by the theories.

Measurement of Double-Polarization Asymmetries in the Quasielastic ${}^{3}{\vec{He}} (\vec{e}, e^{'} d)$ Process

Journal Article Mihovilovic, M. ; Jin, G. ; Long, E. ; ... - Physical Review Letters

We present a precise measurement of double-polarization asymmetries in the ³He(e,e'd) reaction. This particular process is a uniquely sensitive probe of hadron dynamics in 3He and the structure of the underlying electromagnetic currents. The measurements have been performed in and around quasi-elastic kinematics at Q²=0.25(GeV/c)² for missing momenta up to 270MeV/c. The asymmetries are in fair agreement with the state-of-the-art calculations in terms of their functional dependencies on pm and omega, but are systematically offset. Beyond the region of the quasi-elastic peak, the discrepancies become even more pronounced. Thus, our measurements have been able to reveal deficiencies in the mostmore »« less

Measurement of double-polarization asymmetries in the quasi-elastic ${}^{3}{\vec{He}} (\vec{e}, e^{'} p)$ process

Journal Article Mihovilovič, M. ; Jin, G. ; Long, E. ; ... - Physics Letters. B

We report on a precise measurement of double-polarization asymmetries in electron-induced breakup of3He proceeding to pd and ppn final states, performed in quasi-elastic kinematics atQ2= 0.25 (GeV/c)2for missing momenta up to 250 MeV/c. These observables represent highly sensitive tools to investigate the electromagnetic and spin structure of3He and the relative importance of two- and three-body effects involved in the breakup reaction dynamics. The measured asymmetries cannot be satisfactorily reproduced by state-of-the-art calculations of3He unless their three-body segment is adjusted, indicating that the spin-dependent part of the nuclear interaction governing the three-body breakup process is much smaller than previously thought.

Decays of the Three Top Contributors to the Reactor ${\bar{ν}}_{e}$ High-Energy Spectrum, ${}^{92}{Rb}$ , ${}^{96 gs}Y$ , and ${}^{142}{Cs}$ , Studied with Total Absorption Spectroscopy

Journal Article Rasco, B. C. ; Wolińska-Cichocka, M. ; Fijałkowska, A. ; ... - Physical Review Letters

Here, we report total absorption spectroscopy measurements of ⁹²Rb, ⁹⁶^gsY, and ¹⁴²Cs β decays, which are the most important contributors to the high energy ν¯_e spectral shape in nuclear reactors. These three β decays contribute 43% of the ¯νe flux near 5.5 MeV emitted by nuclear reactors. This ν¯_e energy is particularly interesting due to spectral features recently observed in several experiments including the Daya Bay, Double Chooz, and RENO Collaborations. Measurements were conducted at Oak Ridge National Laboratory by means of proton-induced fission of ²³⁸U with on-line mass separation of fission fragments and the Modular Total Absorption Spectrometer.
