Abstract

The neutron capture reaction \(^{10}\)B(n,\(\alpha \))\(^{7}\)Li has been investigated via the Trojan Horse Method from 0 to 1 MeV. The \(\alpha _{0}\) and \(\alpha _{1}\) channels, corresponding to \(^{7}\)Li in its g.s. and 1st excited level respectively, have been analyzed and cross sections have been measured for the two reaction channels. Angular distributions for the \(^{11}\)B energy levels in the explored range have been extracted and compared with literature, while the J\(^{\pi }\) of the level at \(E_{11B}=11.450\) MeV (4 keV before the \(\alpha \) emission threshold) has been clearly determined for the first time.
