Query: On the polarization effects in (p,n) reactions between the A=48
  isobarical states   Isotopical dependence of spin-orbit splitting discovered by us in spectra of
heavy nuclei close to doubly magic ones is checked in polarization effects
arising in charge exchange (p,n) reaction between the A=48 isobarical states.
