    "abstract": "Three kinds of electrostatic modes are experimentally observed to propagate\nalong magnetic-field lines for the first time in the pair-ion plasma consisting\nof only positive and negative fullerene ions with an equal mass. It is found\nthat phase lags between the density fluctuations of positive and negative ions\nvary from 0 to $\\pi$ depending on the frequency and is fixed at $\\pi$ in the\ncases of ion acoustic and ion plasma waves, respectively. In addition, a new\nmode with the phase lag about $\\pi$ appears in an intermediate-frequency band\nbetween the acoustic and plasma waves.",
