Here, we discuss the possibility of showing the existence of [Formula: see text] and [Formula: see text] bound states. Measurement of the single γ-ray from [Formula: see text] and [Formula: see text] systems at rest can directly confirm whether X(1860) and X(1835) are the resonances which are strongly coupled to [Formula: see text]. In addition to the neutral candidate, a charged resonance X - is also proposed to be searched for in [Formula: see text] channel. We find that the data from the Crystal Barrel experiment at LEAR/CERN can be used to confirm the X(1835) observed by BES collaboration. The possibility of measuring the γ spectrum below 100 MeV at the new experiment with cold high intensity [Formula: see text] beam at GSI is discussed. These new techniques can be used to probe the structure of the X(1860) and X(1835) in the future.
