Analysis of residual cross sections from N14+Nb93 reaction: Fusion dynamics of a non- α -cluster projectile

Abstract

In the low-energy region, efforts have been made to understand the fusion mechanism of non-$\ensuremath{\alpha}$-cluster projectiles, such as $^{14}\mathrm{N}$ and $^{19}\mathrm{F}$. However, analyzing the contributing degrees of freedom has been hard in such reactions due to the lack of experimental data. This article reports the measurement of residual cross sections from the $^{14}\mathrm{N}$ induced reaction on $^{93}\mathrm{Nb}$ within the energy range of 42--59 MeV. The residues $^{104}\mathrm{Cd}$, $^{104}\mathrm{Ag}$, $^{103}\mathrm{Ag}$, $^{101}\mathrm{Pd}$, and $^{101m}\mathrm{Rh}$ produced during the reaction were identified using $\ensuremath{\gamma}$-ray spectroscopy. The measured excitation functions have been analyzed with the equilibrium and pre-equilibrium mechanism-based model codes to understand the associated reaction mechanism. A revision of intensity corresponding to the 118.72 keV $\ensuremath{\gamma}$ ray of $^{103}\mathrm{Ag}$ has also been proposed in this article.
