Subbarrier interactions of the oxygen isotopes [PDF]

open access: yesPhysical Review C, 1987
We derive a unified description of the low-energy elastic, inelastic, neutron transfer, and fusion cross sections of systems involving two stable oxygen isotopes. Coupled channels equations with an incoming wave boundary condition are employed, as is the no-recoil approximation; the adiabatic approximation, which violates unitarity, is avoided.

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 ...

Elastic and total reaction cross sections of oxygen isotopes in Glauber theory

open access: yes, 2008
We systematically calculate the total reaction cross sections of oxygen isotopes, $^{15-24}$O, on a $^{12}$C target at high energies using the Glauber theory.

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 ...

Composition and Spatial Distribution Characteristics of Hydrogen and Oxygen Isotopes of Surface Water in Altay, Xinjiang Province

open access: yesYankuang ceshi, 2021

Quenching of spectroscopic factors for proton removal in oxygen isotopes

open access: yes, 2011
We present microscopic coupled-cluster calculations of the spectroscopic factors for proton removal from the closed-shell oxygen isotopes $^{14,16,22,24,28}$O with the chiral nucleon-nucleon interaction at next-to-next-to-next-to-leading order.

Application of Nitrogen and Oxygen Isotopes for Source and Fate Identification of Nitrate Pollution in Surface Water: A Review

open access: yesApplied Sciences, 2018
Nitrate pollution in surface water has become an environmental problem of global concern. The effective way for controlling the nitrate pollution of surface water is to identify the pollution source and reduce the input of nitrate.
