Possibility of modification of the 231Pa Mössbauer spectra due to polarization-selective optical pumping
The possibility of optical pumping of nuclei in solids is considered. In spite of the fact that inhomogeneous and homogeneous linewidths typically exceed the hyperfine splitting in solid hosts it is possible to redistribute the population of the hyperfine nuclear sublevels by means of polarization-selective optical pumping. Such redistribution can be detected by NMR methods or Mössbauer spectroscopic techniques. The latter case is considered in this work. The Mössbauer isotope 231Pa is proposed as a candidate for possible experiment.
