Integrating nuclide specific and dose rate based methods for airborne and ground based gamma spectrometry [PDF]

open access: yes, 2015
Results of joint airborne survey work conducted by SUERC and JAEA are presented, for areas to the north and south of Fukushima Daiichi using four different airborne survey systems, cross calibrated at reference sites in Scotland and near Namie.

Nuclear Reaction Network for Primordial Nucleosynthesis: a detailed analysis of rates, uncertainties and light nuclei yields

open access: yes, 2018
We analyze in details the standard Primordial Nucleosynthesis scenario. In particular we discuss the key theoretical issues which are involved in a detailed prediction of light nuclide abundances, as the weak reaction rates, neutrino decoupling and ...

Short-lived Nuclei in the Early Solar System: Possible AGB Sources [PDF]

open access: yes, 2005
(Abridged) We review abundances of short-lived nuclides in the early solar system (ESS) and the methods used to determine them. We compare them to the inventory for a uniform galactic production model.

Mineral Speciation for CO2 Captured by Potassium Hydroxide

open access: yesChemistryOpen, EarlyView.
Multimodal and deconvolution analysis of the crystalline and amorphous mineral products from the rapid capture of CO2 in aqueous, aqueous‐ethanol, and aqueous‐acetone solutions of potassium hydroxide by complementary single‐crystal and powder X‐ray diffraction, and high field 1H, 13C, and 39K NMR, provides new insight into the speciation of both KHCO3‐

Cosmogenic-nuclide production by primary cosmic-ray protons [PDF]

open access: yes, 1985
The production rates of cosmogenic nuclides were calculated for the primary protons in the galactic and solar cosmic rays. At 1 AU, the long-term average fluxes of solar protons usually produce many more atoms of cosmogenic nuclide than the primary ...

r-Process Lanthanide Production and Heating Rates in Kilonovae [PDF]

open access: yes, 2015
r-Process nucleosynthesis in material ejected during neutron star mergers may lead to radioactively powered transients called kilonovae. The timescale and peak luminosity of these transients depend on the composition of the ejecta, which determines the ...

A Formation Inversion Algorithm Based on Collaborative Fuzzy Gradient Neural Dynamics for Natural Gamma Logging While Drilling

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT A formation inversion algorithm with real‐time performance and accuracy is crucial for natural gamma logging while drilling (LWD). However, traditional inversion algorithms are often limited by high computational resource consumption and insufficient accuracy.

Quantifying sediment discharge from the Bolivian Andes into the Beni foreland basin from cosmogenic 10Be-derived denudation rates

open access: yesBrazilian Journal of Geology
: Enormous volumes of sediment are produced in the Central Andes and are then delivered into the foreland basins of Amazon basin tributaries. While cosmogenic nuclides in sediment are a suitable tool to measure the denudation rates of sediment-producing ...

Direct mass measurements beyond the proton drip-line [PDF]

open access: yes, 2007
First on-line mass measurements were performed at the SHIPTRAP Penning trap mass spectrometer. The masses of 18 neutron-deficient isotopes in the terbium-to-thulium region produced in fusion-evaporation reactions were determined with relative ...
