000002573 520__ $$aISR physics is an interesting way to look for resonant states, which - in case of observation - has a clear signature. This is unique to an e+e- experiments. We present here first studies performed with the early Phase 3 data at Belle II. The Belle II experiment has recorded data corresponding to 89.99 fb-1 integrated luminosity, with which we have performed the analysis of the e+e- -> psi(2S), psi(2S)-> pi+ pi- Jpsi, pi0 pi0 Jpsi, and eta Jpsi.
