Importance of $1n$-stripping process in the ${}^6$Li+${}^{159}$Tb reaction

Abstract

The inclusive cross sections of the $\hat{I}\pm$-particles produced in the reaction ${}^6$Li+${}^{159}$Tb have been measured at energies around the Coulomb barrier. The measured cross sections are found to be orders of magnitude larger than the calculated cross sections of ${}^6$Li breaking into $\hat{I}\pm$ and $d$ fragments, thus indicating contributions from other processes. The experimental cross sections of $1n$-stripping and $1n$-pickup processes have been determined from an entirely different measurement, reported earlier. Apart from incomplete fusion and/ $d$-transfer processes, the $1n$-stripping process is found to be a significant contributor to the inclusive $\hat{I}\pm$-particle cross sections in this reaction.
