Abstract
The spin-dependent energy shifts of glueballs composed of three gluons are studied in the MIT bag model systematically. The mass spectra of the three (TE)3 states and the seven (TE)2(TM) states are given, assuming that ι(1440) and θ(1640) are the(TE) (TM) and (TE)2 glueballs, respectively. We propose the possibility that ξ(2200) state is the 0++(TE)3 glueball. An exotic narrow 1−+ state is also expected to be seen in the radiative decay of J/ψ.
