Abstract
A drastic energy shift and a growth of new splitting lines were observed in the magnetoabsorption spectra of stacking-fault excitons in Bi under high pulsed magnetic fields up to 40 T. The observed magnetic field effects cannot be explained by a conventional effective-mass approximation or the bielectron model, but were successfully understood on the basis of a model of cationic excitons which are perturbed by a specific stacking fault.
