This paper reports on elastic scattering excitation functions for the reaction $^{9}$Li+$^{4}$He measured at backward angles in the centre of mass energy range 5 MeV ≤ E≤c.m.9.5 MeV, with the aim of investigating the possible existence of molecular resonances which have been predicted to exist in the case of neutron-rich B-isotopes. Due to the short lifetime of $^{9}$Li, the experiment necessitated the use of inverse kinematics on a gaseous $^{4}$He target. The Thick Target Inverse Kinematics technique was used which allowed for the measurement of the full excitation function in a single $^{9}$Li run. Broad resonances were observed in the excitation region for $^{13}$B 15 MeV ≤ Ex≤20 MeV. To understand the nature of such broad structures, various theoretical attempts are reported concerning possible reaction mechanisms for this neutron rich reaction. The most promising approach to interpret the data is within the orbiting reaction scenario. |
