000000705 520__ $$aThe study of initial state radiation (ISR) events at Belle II provides independent and contiguous measurements of hadronic cross sections in and also contributes to the investigation of low-mass resonances spectroscopy. Belle II has the advantage that data at different energies will be accumulated at the same time, making the ISR analysis much simpler than other experiments where the data was taken at some fixed energy points. In addition, Belle II can produce events above 4.6 GeV, which is currently the maximum energy of BEPCII. With larger than 10 ab^-1 data sample at Belle II, we will do ISR processes e^+e^- to pi^+ pi^-J/psi, pi^+ pi^- psi(2S), K^+ K^- J/psi, gamma X(3872), etc. Sensitivity studies of e^+e^- to Y(4260) to pi^+pi^- J/psi and e^+e^- to Y(4360,4660) to pi^+ pi^-\psi(2S) under different integrated luminosities are ongoing.
