  We discuss possible search for optical transitions in Sm13+ and Sm14+ using
ab initio calculations of differential dynamic polarizability. We calculate
dynamic polarizability for M1 transition between first and second excited
states of Sm14+ . Transition amplitudes and energies within optical range for
states that contribute to the polarizability of the mentioned transition are
presented. Employing simple analytical formula for polarizability data in the
vicinity of a resonance and assuming that several values of the polarizability
for different laser frequencies will be measured one can find the accurate
position of the resonance. Results of similar calculations of amplitudes and
energies of states that contribute to the polarizability of the M1 transition
between ground and first excited states of Sm13+ are also presented.
