Radiative capture of proton by ⁹Be(p, γ)¹⁰B at low energy

Abstract

Radiative capture p+9Be → 10B+γ at energies bearing astrophysical importance is a key process for the spectroscopic study of 10B. In this work, we consider the radiative capture cross-section for the 9Be(p, γ)10B within the framework of the potential model and the R-matrix method for the multi-entrance channel cases. In certain cases, when the potential fails, therefore, the R-matrix approach is better to use for the description of partial components of the cross-section that have sharp or broad resonances. For all possible electric and magnetic dipole transitions, partial components of the astrophysical S-factor are computed. The computed value of the total S-factor at zero energy is consistent with the reported results.

Re-analysis of radiative capture11C(p, γ)12N at low energy

“…We employed the PM approach, in which the modified form of the Woods-Saxon potential is used as nuclear input for the computation of the bound-state wave function. Within the specified range, the model accurately reproduced the measured results for the cross-section and nuclear rates [16][17][18]. Resonant and non-resonant transitions can be found in the matrix element.…”

Magnetic dipole transitions in 9Be(p,γ)10B

“…One should note that in the present work the value of spectroscopic factor for the 9 Be(p,γ) 10 B was selected as unity. Therefore, the parameters that are mentioned in table 2 for potential (8) are reliable for the description of the astrophysical S-factor. The computed S-factor via M 1 resonant transition at zero energy in the present work is 0.073 keV•b.…”

“…Similarly, in ref. [8] they employed the hybrid model (combination of PM and R-matrix) and computed both the transition from the continuum J π = 2 − and J π = 1 − to the ground state, first excited state, second excited state and third excited state of 10 B, respectively. Their computed S(0) was in good comparison with the measured data.…”

“…10 B has various continuum and bound states [18]. In our last few studies we take into account the E1 transitions from the continuum to the three low lying bound states [7], similarly, we employed the hybrid model the combination of PM and Rmatrix method for the E1 transitions (employing the PM) and M 1 (employing the R-matrix method) transitions [8].…”

Re-examination of radiative capture of deuteron 3He(d,γ)5Li at low energy

“…The Woods-Saxon potential has a good asymptotic behavior at high distances when compared with the Gaussian potential. Within the particular range of energy and temperature, the model is precise in depicting the observed nuclear function values [15][16][17][18][19][20][21][22][23]. In the DC calulation the matrix components exhibit both the resonant and non-resonant transitions.…”
