“…Both CDCC calculations and the Hulthén-ADWA reproduce the shape of experimental data but RSC-ADWA overestimates the data at larger angles for the states at E x = 0.84 and 6.8 MeV. The spectroscopic factors extracted with CDCC are larger than those determined in [20], but this difference decreases with the excitation energy.…”

We apply the newly developed local-equivalent CDCC model to the (d, p) reaction recently measured in inverse kinematics with isomeric 26m Al beam [20]. Because of the 0 + spin of this isomer transfers to the final 27 Al states will involve only one orbital momentum, thus facilitating extraction of spectroscopic factors.…”

Reduced sensitivity of the (d,p) cross sections to the deuteron model beyond the adiabatic approximation

It has recently been reported [Phys. Rev. Lett. 117, 162502 (2016)] that (d, p) cross sections can be very sensitive to the n-p interactions used in the adiabatic treatment of deuteron breakup with nonlocal nucleon-target optical potentials. To understand to what extent this sensitivity could originate in the inaccuracy of the adiabatic approximation we have developed a leading-order localequivalent continuum-discretized coupled-channel model that accounts for non-adiabatic effects in the presence of nonlocality of nucleon optical potentials. We have applied our model to the astrophysically relevant reaction 26m Al(d, p) 27 Al using two different n-p potentials associated with the lowest and the highest n-p kinetic energy in the short-range region of their interaction, respectively. Our calculations reveal a significant reduction of the sensitivity to the high n-p momenta thus confirming that it is mostly associated with theoretical uncertainties of the adiabatic approximation itself. The non-adiabatic effects in the presence of nonlocality were found to be stronger than those in the case of the local optical potentials. These results argue for extending the analysis of the (d, p) reactions, measured for spectroscopic studies, beyond the adiabatic approximation.

“…Among these is the possibility to study nuclear reactions on strongly populated isomeric states within the beam. In some cases, an isomer may be of interest for probing otherwise inaccessible nuclear structure information [1][2][3][4]; in other cases, such as 26 Al and 38 K, astrophysical reactions on the isomer can play an important role in the reaction network [5].…”

In radioactive ion beam experiments, beams containing isomers can be of interest in probing nuclear structure and informing astrophysical reaction rates. While the production of mixed in-flight ground state and isomer beams using nucleon transfer can be generally understood through distorted wave Born approximation methodology, low-spin isomer production via fast fragmentation is relatively unstudied. To attain a practical understanding of low-spin isomer production using fast fragmentation beams, a test case of 38 K= 38m K was studied at the National Superconducting Cyclotron Laboratory's ReAccelerated Beam facility. Starting from LISE++ predictions, the fragmentation momentum distribution was sampled to determine isomer production. In addition, the effects of the gas stopper gradient and charge breeding times were examined. In the case of 38 K, isomer production peaks at ∼57%. This maximum is observed just off the LISE++ predicted optimum magnetic rigidity, with only small losses in beam intensity within a few percent of this optimum rigidity setting. Control of the isomer fraction was also achieved through the modification of charge breeding times. Fast fragmentation appears to be a feasible method for production of low-spin isomeric beams, but additional study is necessary to better describe the mechanism involved.

Expanding Nuclear Physics Horizons with the Gamma Factory

et al. 2022

The Gamma Factory (GF) is an ambitious proposal, currently explored within the CERN Physics Beyond Colliders program, for a source of photons with energies up to ≈400 MeV and photon fluxes (up to ≈1017 photons s−1) exceeding those of the currently available gamma sources by orders of magnitude. The high‐energy (secondary) photons are produced via resonant scattering of the primary laser photons by highly relativistic partially‐stripped ions circulating in the accelerator. The secondary photons are emitted in a narrow cone and the energy of the beam can be monochromatized, down to 10−3–10−6 level, via collimation, at the expense of the photon flux. This paper surveys the new opportunities that may be afforded by the GF in nuclear physics and related fields.
