The probability that a nucleus will absorb a neutron—the neutron capture cross-section—is important to many areas of nuclear science, including stellar nucleosynthesis, reactor performance, nuclear medicine and defence applications. Although neutron capture cross-sections have been measured for most stable nuclei, fewer results exist for radioactive isotopes, and statistical-model predictions typically have large uncertainties1. There are almost no nuclear data for neutron-induced reactions of… 
NG-TRAP: Measuring neutron capture cross-sections of short-lived fission fragments
We lack significant nuclear physics input to understand the rapid-neutron capture (r-)process fully. The r-process is the source of half the elements heavier than iron and the only way to produce the
Neutron Capture Cross Sections of Radioactive Nuclei
Alternative methods to calculate neutron capture cross sections on radioactive nuclei are reported using the theory of Inclusive Non-Elastic Breakup (INEB) developed by Hussein and McVoy [1]. The
The importance of charged particle reactions in the r-process on supernovae and neutron stars
We propose a $(p,xn)$ mechanism with dynamic production as a new set of nuclear reactions that could produce high density neutrons and explain the r- and rp-elements. We calculate the rate of thorium
New capability for indirect neutron capture measurements: The DICER instrument at LANSCE
The Device for Indirect Capture on Radionuclides (DICER) implements a new indirect technique for (n,γ) studies in which the neutron capture rate is determined from analysis of resonance neutron
Measurement of 90Zr(n,2n)89Zr and 90Zr(n,p)90mY reaction cross-sections in the neutron energy range of 10.95 to 20.02 MeV
The (n,2n) and (n,p) reaction cross-sections of 90Zr isotope have been measured in 10.95 to 20.02 MeV neutron energy range by using activation and off-line γ-ray spectrometric technique.
Aqueous harvesting of Zr88 at a radioactive-ion-beam facility for cross-section measurements
Isotope harvesting is a method of collecting the long-lived radioisotopes that build up during the operation of ion-beam facilities in a way that is useful for subsequent research. As a demonstration
Zirconium isotope found to be a neutron poison
Zirconium alloys are widely used as cladding material in nuclear reactors due to their neutron transparency. Now, it is shown that 88Zr has a surprisingly high neutron capture cross-section exceeding
Isotope harvesting at FRIB: additional opportunities for scientific discovery
The Facility for Rare Isotope Beams (FRIB) at Michigan State University provides a unique opportunity to access some of the nation's most specialized scientific resources: radioisotopes. An excess of
Separation of zirconium and hafnium from early actinides and rare earth elements with eichrom’s pb resin in HCl
The separation of zirconium and hafnium isotopes from the early actinides and rare earth elements (REE) with Eichrom’s Pb resin has been studied. Batch studies were performed to characterize the

Statistical features of the thermal neutron capture cross sections
We discuss the existence of huge thermal neutron capture cross sections in several nuclei. The values of the cross sections are several orders of magnitude bigger than expected at these very low

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
Neutron energy spectra and yields from the 7Li(p, n) reaction for nuclear astrophysics
Neutrons produced by the 7Li(p, n)7Be reaction close to threshold are widely used to measure the cross section of s-process nucleosynthesis reactions. While experiments have been performed so far
Measurement of the Rb-85 and Rb-87 capture cross sections for s-process studies
The neutron capture cross sections of Rb-85 and Rb-87 using the TOF technique are measured. From the differential data, Maxwellian-averaged capture cross sections are computed as a function of

The Influence of Xenon-135 on Reactor Operation
Xenon-135 is a product of U-235 fission and has a very large neutron-capture cross section. It also decays radioactively with a half-life of 9.1 hours. Little of the Xe-135 results directly from
Neutron capture cross section of Ti-44
The cross section for thermal neutron capture by radioactive Ti-44 was measured to be sigma(gamma) = 1.1 +/- 0.2 b. This result was shown to be in agreement with a direct capture calculation.
