Abstract
Recently, the very small value was found in Os, which is 7(4) W.u. \textbf{and} much smaller than the values of adjacent nuclei Os, 74(13) W.u. and 97(9) W.u.. With the help of a new technique ``SU(3) analysis" and a new explanatory framework of the B(E2) anomaly, it was found that, the anomaly really can exist. In this paper, we discuss the anomaly in Os for the first time. Four results are used to fit the experimental data in Os successfully. This implies that the level-crossing or level-anticrossing explanation is more reasonable.
