Abstract

The thick target inverse kinematic method was applied to the study of isobaric analog states in the neutron-rich nucleus $^{9} Li .$ For this purpose, an excitation function for $^{8} He + p$ elastic scattering was measured in the center-of-momentum energy range from 1.6 to 5.8 MeV. Three $T = 5 / 2$ states in $^{9} Li$ (isobaric analogs of $^{9} He)$ were observed. Restrictions on the spin-parity assignments are provided according to R-matrix calculations, and conclusions regarding the structure of $^{9} He$ are given.
