Nuclear aspects of stellar and explosive nucleosynthesis
(Springer Nature, 2001)
The majority of nuclear reactions in astrophysics involve unstable nuclei which are not yet fully accessible by experiments. Therefore, there is high demand for reliable predictions of cross sections and reaction rates by ...
High-resolution neutron capture and transmission measurements, and the stellar neutron-capture cross section of Sr-88
(2000-11)
We have made new and improved measurements of the neutron capture and total cross sections for Sr-88 at the Oak Ridge Electron Linear Accelerator (ORELA). Improvements over previous measurements include a wider incident ...
Sm-147(n,alpha) cross section measurements from 3 eV to 500 keV : Implications for explosive nucleosynthesis reaction rates
(2000-10)
We have measured the Sm-147(n, alpha) cross section from 3 eV to 500 keV. These data were used to test nuclear statistical models which must be relied on to calculate the rates for as yet unmeasurable reactions occurring ...
Neutron cross sections for nucleosynthesis studies
(2000-09)
Previous compilations of (n, gamma) cross sections of relevance for neutron capture nucleosynthesis in the big bang and in the slow neutron capture process (s process) have been updated to encompass information available ...
Experimental simulation of a stellar photon bath by bremsstrahlung: the astrophysical gamma-process
(2000-08-31)
The nucleosynthesis of heavy proton-rich nuclei in a stellar photon bath at temperatures of the astrophysical gamma-process was investigated where the photon bath was simulated by the superposition of bremsstrahlung spectra ...
Capture of a particles by isospin-symmetric nuclei
(2000-08-14)
The reaction rates for ct capture processes on self-conjugate nuclei in the mass range A = 20-40 have been investigated. The rates were calculated using the statistical model code NON-SMOKER taking into account isospin ...
The 1999 update of stellar neutron capture rates
(American Institute of Physics (AIP), 2000)
Prediction of astrophysical reaction rates : Methods, data needs, and consequences for nucleosynthesis studies
(American Institute of Physics (AIP), 2000)
The majority of nuclear reactions in astrophysics involve unstable nuclei which are not fully accessible by experiments yet. Therefore, there is high demand for reliable predictions of cross sections and reaction rates by ...
Astrophysical reaction rates from statistical model calculations
(2000)
Theoretical reaction rates in the temperature range 0.01 x 10(9) less than or equal to T(K) less than or equal to 10.0 x 10(9) are calculated in the statistical model (Hauser-Feshbach formalism) for targets with 10 less ...
