42 superdeformed (SD) bands, which have a pronounced increase in the dynamic moment of inertia J{sup (2)} with rotational frequency {h_bar}{omega} in the A{approximately}190 region, are studied using the exponential model with pairing attenuation. The level spins are suggested and the parameters J{sub 0} and {Delta}{sub 0} are determined for these bands. The excellent agreement between the calculated E{sub {gamma}} and the observed E{sub {gamma}} gives good support to the model. The parameters J{sub 0}, {Delta}{sub 0} and the band head moment of inertia J{sub b.h.} show evident odd-even effects which may indicate different intrinsic structure in the studied SD nuclei. {copyright} {ital 1997} {ital The American Physical Society}
