Quasifree (p, 2p) Reactions on Oxygen Isotopes: Observation of Isospin Independence of the Reduced Single-Particle Strength.

open access: yesPhysical Review Letters, 2018
Quasifree one-proton knockout reactions have been employed in inverse kinematics for a systematic study of the structure of stable and exotic oxygen isotopes at the R^{3}B/LAND setup with incident beam energies in the range of 300-450  MeV/u.

Hydrochemical and stable isotopes (δ2H and δ18O) changes of groundwater from a spring induced by local earthquakes, Northwest China

open access: yesFrontiers in Earth Science, 2023
It has been well reported that earthquakes can cause changes in groundwater chemistry and isotopes, and much of those changes were occurred in wells or hot springs; however, changes in cold spring caused by local small earthquakes have received less ...

Low-lying continuum states of drip-line Oxygen isotopes [PDF]

open access: yes, 2015
Low-lying continuum states of exotic oxygen isotopes are studied, by introducing the Continuum-Coupled Shell Model (CCSM) characterized by an infinite wall placed very far and by an interaction for continuum coupling constructed in a close relation to ...

Cretaceous sea-surface temperature evolution: Constraints from TEX86 and planktonic foraminiferal oxygen isotopes

open access: yes, 2017
It is well established that greenhouse conditions prevailed during the Cretaceous Period (~ 145–66 Ma). Determining the exact nature of the greenhouse-gas forcing, climatic warming and climate sensitivity remains, however, an active topic of research ...

Progress of Analytical Techniques and Application of Triple Oxygen Isotopes in Dissolved Oxygen

open access: yesJournal of Isotopes
Oxygen is one of the essential elements in Earth's ecosystem,with stable isotopes including δ16O,δ17O,and δ18O. The composition of oxygen stable isotopes (δ17O,δ18O) exhibits different fractionation patterns in various biogeochemical reactions,making ...
