Title: Application of an ab initio $S$ matrix to data analysis of transfer reactions to the continuum populating ${}^{11}{Be}$

Abstract

Recently, the bound and continuum spectrum of ¹¹Be has been calculated within the ab initio no-core shell model with continuum (NCSMC) method, with the parity inversion in the ground state successfully reproduced. Here, the continuum spectrum obtained is in agreement with known experimental levels. The S matrix contained in the NCSMC continuum wave functions of the n + ¹⁰Be system is used in this work for the first time in a transfer-to-the-continuum (TC) reaction calculation. The TC approach is applied to study the excitation energy spectrum of ¹¹Be measured in the ⁹Be( ¹⁸O, ¹⁶O) ¹¹Be reaction at 84 MeV. Previously known levels are confirmed and theoretical and experimental evidence for a 9/2 ⁺ state at E _x = 5.8 MeV is given, whose configuration is thought to be ¹⁰Be(2 ⁺)+n( d _5/2).

${}^{7}{Be}$ and ${}^{7}{Li}$ nuclei within the no-core shell model with continuum

Journal Article Vorabbi, Matteo ; Navrátil, Petr ; Quaglioni, Sofia ; ... - Physical Review C

The production of $^7Be$ and $^7Li$ nuclei plays an important role in primordial nucleosynthesis, nuclear astrophysics, and fusion energy generation. The $^3He(α,γ) ^7Be$ and $^3H(α,γ) 7Li$ radiative-capture processes are important to determine the $^7Li$ abundance in the early universe and to predict the correct fraction of $pp$ -chain branches resulting in $^7Be$ versus $^8B$ neutrinos. The $^6Li(p,γ) ^7Be$ has been investigated recently hinting at a possible cross section enhancement near the threshold. The $^6Li (n,^3H) ^4He$ process can be utilized for tritium breeding in machines dedicated to fusion energy generation through the deuteron-tritium reaction, and is a neutron cross sectionmore »« less

$(d, n)$ proton-transfer reactions on ${}^{9}{Be}, {}^{11}B, {}^{13}C, {}^{14, 15}N$ , and ${}^{19}F$ and spectroscopic factors at $E_{d} = 16 MeV$

Journal Article Febbraro, Michael T. ; Becchetti, F. D. ; Torres-Isea, R. O. ; ... - Physical Review C

The (d,n) reaction has been studied with targets of ⁹Be, ¹¹B, ¹³C, ^14,15N, and 19F at E _d = 16MeV using a deuterated liquid-scintillator array. Advanced spectral unfolding techniques with accurately measured scintillator response functions were employed to extract neutron energy spectra without the need for long-path neutron time-of-flight. An analysis of the proton-transfer data at forward angles to the ground states of the final nuclei, using finite-range distorted-wave Born approximation analysis with common bound-state, global, and local optical-model parameter sets, yields a set of self-consistent spectroscopic factors. These are compared with the results of several previous time-of-flight measurements, mostmore »« less

Structure of $0^{+}$ excitations in the mass $A \approx 100$ region: $0_{2}^{+}$ bands in ${}^{98}{Sr}$ and ${}^{100}{Zr}$

Journal Article Urban, W. ; Rząca-Urban, T. ; Wiśniewski, J. ; ... - Physical Review C

0 ⁺ ₂ bands in ⁹⁸Sr and ¹⁰⁰Zr, populated in spontaneous fission of ²⁴⁸Cm and ²⁵²Cf, have been studied using the Eurogam2 and Gammasphere arrays. Phenomenological classification of excited 0 ⁺ levels in even-even nuclei of the A ≈ 100 region into four categories is presented and an interpretation for each category is proposed. Highly deformed 0 ⁺ ₁ ground states and low-energy 0 ⁺ ₂ levels in both nuclei are probably due to the 2p-2h excitation of two neutrons from the 9/2 ⁺[404] extruder to the low-Ω prolate and the 11/2 ^–[505] oblate orbitals originating from the h _11/2more »« less

New $γ$ -ray transitions observed in ${}^{19}{Ne}$ with implications for the ${}^{15}O (α, γ) {}^{19}{Ne}$ reaction rate

Journal Article Hall, Matt R. ; Bardayan, D. W. ; Baugher, T. ; ... - Physical Review C

The ¹⁵O(α,γ) ¹⁹Ne reaction is responsible for breakout from the hot CNO cycle in type I x-ray bursts. Understanding the properties of resonances between E _x=4 and 5 MeV in ¹⁹Ne is crucial in the calculation of this reaction rate. The spins and parities of these states are well known, with the exception of the 4.14- and 4.20-MeV states, which have adopted spin-parities of 9/2 ^- and 7/2 ^-, respectively. γ-ray transitions from these states were studied using triton-γ – γ coincidences from the ¹⁹F( ³He,tγ) ¹⁹Ne reaction measured with the GODDESS (Gammasphere ORRUBA Dual Detectors for Experimental Structure Studies)more »« less

Proton Shell Evolution below ${}^{132}{Sn}$ : First Measurement of Low-Lying $β$ -Emitting Isomers in ${}^{123, 125}{Ag}$

Journal Article Chen, Z. Q. ; Li, Z. H. ; Hua, H. ; ... - Physical Review Letters

The β-delayed γ-ray spectroscopy of neutron-rich ^123,125Ag isotopes is investigated at the Radioactive Isotope Beam Factory of RIKEN, and the long-predicted 1/2 ^- β-emitting isomers in ^123,125Ag are identified for the first time. With the new experimental results, the systematic trend of energy spacing between the lowest 9/2 ⁺ and 1/2 ^- levels is extended in Ag isotopes up to N = 78, providing a clear signal for the reduction of the Z = 40 subshell gap in Ag towards N = 82. Shell-model calculations with the state-of-the-art V _MU plus M3Y spin-orbit interaction give a satisfactory description of themore »« less
