摘要：

High-spin states in( 84)Rb are studied by using the Zn-70(O-18, p3n)84Rb reaction at a beam energy of 75 MeV. Three high-lying negative-parity bands are established, whose level spacings are very regular, i.e., there is no signature splitting. The dipole character of the transitions of these three bands is assigned by the ?-? directional correlations of oriented states (DCO) intensity ratios and the multipolarity M1 is suggested by analogy with multi particle excitations in neighboring nuclei. Strong M1 and weak or no E2 transitions are observed. All these characteristic features show they are magnetic rotational bands.
