Investigating halo features with the $^{11}$Be(p, d)$^{10}$Be transfer reaction at 110 MeV at TRIUMF-ISAC II

One-neutron transfer reactions are being used to study single-particle neutron states in nuclei. For one-neutron halo nuclei, such as $^{11}$Be, the (p,d) reaction enables the removal of the halo neutron or of one of the core neutrons. This way, it is possible to simultaneously study the halo wavefunction of the $^{11}$Be ground-state but also possible excited halo states in $^{10}$Be. The $^{11}$Be(p, d)$^{10}$Be transfer reaction at 10 MeV/nucleon is being investigated at the TRIUMF-ISAC II facility with a compact silicon array and the TRIUMF ISAC Gamma-Ray Escape-Suppressed Spectrometer (TIGRESS). The goal of this experiment is to study halo states in $^{11}$Be and $^{10}$Be created by the removal of a single neutron from $^{11}$Be. An initial experiment was carried out last summer and preliminary results will be presented.
