【Abstract】 Usually, for Mssbauer mirror spectra folding procedure is an effective way to eliminate the geometric effect of the base line, and to raise the data acquisition efficiency. Folding is often proceeded by taking the center of mirror spectra as folding point, but a disadvantage of obvious line-broadening, resulted by the fact that the Doppler velocity lags behind the drive signal is usually overlooked. In this paper, a new approach was developed, which could avoid the above problem.更多还原
