We present a measurement of the partial and differential photoionization cross sections for production of the fine-structure states of Cl+ P-3(J) in the region of the (3)p(41)Dnl (l = 0,2) autoionizing resonances. All series of resonances show distinctive behavior for the J=2 to J=1 cross-section ratio. The angular distribution parameter beta was also measured for the two principal ionic states (J = 1,2). The behavior of beta is very similar for both J=1,2 channels, except at the LS-forbidden nd(2)S resonance series, where the J=2 channel shows a pronounced dip that indicates an important contribution from the parity-unfavored epsilon d photoelectron waves. The widths of the 4d(2)S, 6s(2)D, and 7s(2)D resonances were measured and the results are compared with available theoretical calculations. [S1050-2947(97)08010-4].
