We have studied the nucleus ${}_{}{}^5{}_{}{}^{}\mathrm{Li}$ within a multichannel resonating group calculation based on many-body p+α and d${+}^3$He configurations and pseudostates as well as on effective nucleon-nucleon interactions containing central, spin-orbit, and tensor components. The known levels in ${}_{}{}^5{}_{}{}^{}\mathrm{Li}$, identified by the p+α phase shifts and the ${}_{}{}^3{}_{}{}^{}\mathrm{He}$(d,p${)}^4$He fusion cross section, can consistently be described by our approach. Special distortion effects in the sense of Tang and collaborators are discussed for these states.
