The fractionally quantized Hall states at = (1/3 and (2/5 filling factors have been studied by finite-size numerical calculations allowing for reversed spins. I report on the fractionally charged defect states, including their spin distribution, and the spin-wave type neutral collective mode of the (1/3 state. The defects of the (2/5 unpolarized incompressible fluid are found to be spin- (1/2 objects leading to singlet and triplet neutral collective modes. Possible relevance to experiments are discussed.
