Photoabsorption spectra of He N + ${{\rm{He}}_N^ + }$ clusters, N=5-9, have been calculated using a diatomics-in-molecules like electronic structure model and a path-integral Monte Carlo sampling method. A qualitative change in the calculated spectra has been observed at N=9, which has been interpreted in terms of a structural transformation in the clusters consisting in a transition from trimer-like ionic cores observed for N≤7 to dimer-like ionic cores prevailing in He 9 + ${{\rm{He}}_9^ + }$ through an intermediate state (comparable abundances of both types of ionic cores) observed in He 8 + ${{\rm{He}}_8^ + }$ . The calculated spectra have been thoroughly compared with an earlier calculation on He 3 + ${{\rm{He}}_3^ + }$ , He 4 + ${{\rm{He}}_4^ + }$ , and He 10 + ${{\rm{He}}_{10}^ + }$ reported from our group and data available for the same cluster sizes from an experiment.
