摘要：

Quasi-elastic scattering by semiflexible rings is discussed with a modified version of an earlier theory due to Soda and Berg. The modified theory automatically yields correct results in the highly flexible Gaussian limit, but is found to be erroneous at very high degrees of stiffness. For moderate degrees of stiffness, the results obtained for the first cumulant should be reliable. © 1990.
