In this work, we show, within the framework of renormalized nuclear field theory and of the induced reaction surrogate formalism, that the highly debated 10Li structure, studied in a recent high statistics 9Li ($$\textit{d,p}$$) 10Li one-neutron transfer experiment, is consistent with, or better, requires, the presence of a virtual 1/2+ state of similar single-particle strength than that of the 1/2– resonance at 0.45 ± 0.03 MeV. Based on continuum spectroscopy self-energy techniques, we find that the physical mechanism responsible for parity inversion in $$^{10}_3$$Li is the same as that at the basis of the similar phenomenon observed in $$^{11}_4$$Be and as that needed in 11 Li to have an important $$\textit{s}$$-wave ground-state component. In particular the strong dynamical coupling between the $$s_{1/2}$$ and the $$d_{5/2}$$ states, mediated by the quadrupole vibration of the core 9Li. A phenomenon which also affects the strength distribution of the $$d_{5/2}$$ state, in particular, in the energy range of 3–4.5 MeV. Furthermore, this mechanism is also consistent with the (normal) sequence of the $$1_{p_{1/2}}$$ and $$2_{s_{1/2}}$$ levels in the $$\textit{N}$$ = 7 isotones $$^{12}_5$$B and $$^{13}_6$$C. The main aim of the present Rapid Communication is that of treating structure and reactions on equal footing and in a common language. In other words, the calculation of the 9Li ($$\textit{d,p}$$) 10Li reaction as a single conceptual step from individual single-particle motion and collective vibrations to absolute double differential cross sections of renormalized virtual and resonant final states, which can be directly compared with experiment.
