The electromagnetic transition rates for all the high spin levels of the yrast sequence of {sup 109}Ag have been measured. The observed behavior of the magnetic dipole transition rates as a function of angular momentum establishes that there is a sudden change in rotation axis associated with rotational alignment of two neutrons. The projected shell model calculations give a consistent picture of the observed phenomena in {sup 109}Ag.
