Title: Measurements of the ${}^{169}{Tm} (n, 2 n) {}^{168}{Tm}$ cross section from threshold to 15 MeV

Abstract

Measurements of the ¹⁶⁹Tm(n,2n)¹⁶⁸Tm cross section have been performed via the activation technique at 13 energies between 8.5 and 15.0 MeV. The purpose of this comprehensive data set is to provide an alternative diagnostic tool for obtaining subtle information on the neutron energy distribution produced in inertial confinement deuterium-tritium fusion experiments at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory. In conclusion, the ¹⁶⁹Tm(n,2n)¹⁶⁸Tm reaction not only provides the primary 14-MeV neutron fluence, but also the important down-scattered neutron fluence, the latter providing information on the density achieved in the deuterium-tritium plasma during a laser shot.

Journal Article Gooden, M. E. ; Bredeweg, T. A. ; Champine, B. ; ... - Physical Review C

At the National Ignition Facility, experiments are being performed to measure charged-particle stopping powers in the previously unexplored warm dense plasma regime. These measurements are done using reaction-in-flight (RIF) neutrons from an inertial confinement fusion system. RIF neutrons are produced with a continuum of energies up to 30 MeV. By making activation measurements utilizing threshold reactions for neutrons in the energy range of 15 < E n < 30 MeV , the number of RIF neutrons can be determined and from this the stopping power of the deuterium and tritium ions that produced the RIF neutrons can be inferred.

¹⁶⁹Tm(n,2n)¹⁶⁸Tm and ¹⁶⁹Tm(n,3n)¹⁶⁷Tm cross-section measurements from 15 to 21 MeV

Journal Article Finch, S. W. ; Bhike, M. ; Krishichayan, None ; ... - Physical Review C

The ¹⁶⁹Tm(n,2n)¹⁶⁸Tm and ¹⁶⁹Tm(n,3n)¹⁶⁷Tm cross sections have been measured in the neutron energy range between 15 and 21 MeV using the ³H(d,n) ⁴He neutron source reaction. The ¹⁶⁹Tm(n,3n) ¹⁶⁷Tm data are intended to provide an accurate database for interpreting so-called reaction-in-flight neutron yields, which provide a sensitive tool for studying properties of the deuterium-tritium plasma created in inertial confinement fusion laser shots at the National Ignition Facility at Lawrence Livermore National Laboratory. The data are compared to previous data and evaluations for the reaction studied and are found to be in good agreement with the ENDF/B-VIII.0 evaluation, although small adjustmentsmore »« less

Journal Article Krishichayan, . ; Bhike, M. ; Tornow, W. ; ... - Physical Review C

In this study, the cross section for the ²³⁸U(n,2n)²³⁷U reaction has been measured in the incident neutron energy range from 6.5 to 14.8 MeV in small energy steps using an activation technique. Monoenergetic neutron beams were produced via the ²H( d,n ) ³He and ³H ( d,n ) ⁴He reactions. ²³⁸U targets were activated along with Au and Al monitor foils to determine the incident neutron flux. The activity of the reaction products was measured in TUNL's low-background counting facility using high-resolution γ-ray spectroscopy. The results are compared with previous measurements and latest data evaluations. Statistical-model calculations, based on themore »« less

In-Beam $γ$ -Ray Spectroscopy of ${}^{34, 36, 38}{Mg}$ : Merging the $N = 20$ and $N = 28$ Shell Quenching

Journal Article Doornenbal, P. ; Scheit, H. ; Takeuchi, S. ; ... - Physical Review Letters

Neutron-rich N = 22, 24, 26 magnesium isotopes were studied in this paper via in-beam γ-ray spectroscopy at the RIKEN Radioactive Isotope Beam Factory following secondary fragmentation reactions on a carbon target at ≈ 200 MeV /nucleon. In the one- and two-proton removal channels from ³⁹Al and ⁴⁰Si beams, two distinct γ-ray transitions were observed in ³⁸Mg, while in the one-proton removal reaction from ³⁷Al a new transition was observed in addition to the known 2⁺₁ → 0 ⁺_g.s. decay. From the experimental systematics and comparison to theoretical predictions it is concluded that the transitions belong to the 2⁺₁ →more »« less

Cross section measurements for neutron inelastic scattering and the $(n, 2 n γ)$ reaction on ${}^{206}{Pb}$

Journal Article Negret, A. ; Mihailescu, L. C. ; Borcea, C. ; ... - Physical Review. C, Nuclear Physics

We measured excitation functions for γ production associated with the neutron inelastic scattering and the (n, 2n) reactions on ²⁰⁶Pb from threshold up to 18 MeV for about 40 transitions. Two independent measurements were performed using different samples and acquisition systems to check consistency of the results. Moreover, the neutron flux was determined with a ²³⁵U fission chamber and a procedure that were validated against a fluence standard. For incident energy higher than the threshold for the first excited level and up to 3.5 MeV, estimates are provided for the total inelastic and level cross sections by combining the presentmore »« less
