Building Mexican isoscapes: Oxygen and hydrogen isotope data of meteoric water sampled across Mexico
Data in Brief, 2021 Oxygen and hydrogen isotope data of meteoric water samples are compiled from several States across Mexico. This dataset includes 287 oxygen and hydrogen (and deuterium excess) isotope data corresponding to meteoric water collected from the surface ...

Subbarrier interactions of the oxygen isotopes [PDF]
Physical 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.

Linear Responses in Time-dependent Hartree-Fock-Bogoliubov Method with Gogny Interaction [PDF]
, 2012 A numerical method to integrate the time-dependent Hartree-Fock Bogoliubov (TDHFB) equations with Gogny interaction is proposed. The feasibility of the TDHFB code is illustrated by the conservation of the energy, particle numbers, and center-of-mass in ...

Sedimentary pyrite sulfur isotopes track the local dynamics of the Peruvian oxygen minimum zone
Nature Communications, 2021 To explore the importance of local vs. global sulfur-cycle controls on variations in pyrite sulfur isotopes, the authors couple carbon-nitrogen-sulfur concentrations and stable isotopes of sediments from the Peruvian oxygen minimum zone, identifying a ...

Ab-initio computation of neutron-rich oxygen isotopes [PDF]
, 2009 We compute the binding energy of neutron-rich oxygen isotopes and employ the coupled-cluster method and chiral nucleon-nucleon interactions at next-to-next-to-next-to-leading order with two different cutoffs.

Do oxygen isotope values in collagen reflect the ecology and physiology of neotropical mammals?
Frontiers in Ecology and Evolution, 2015 Stable isotope data provide insight into the foraging ecology of animals. Traditionally, carbon and nitrogen isotope values have been used to infer dietary and habitat preferences.
