Spectropolarimetry of RCrB 4>
 New  spectra of the peculiar
star   R CrB  at deep minimum light were  obtained in 2001  by
V.Klochkova,
V.Panchuk  and
 M.Yushkin  
with the echelle spectrometer
 PFES 
inside the prime focus of the telescope  BTA 
in combination with an analyzer of linear polarization
at the different position angles P2.
 Due to strong weakening of a photospheric spectrum of the
star we can see three components of the spectrum: a continuum
devoid of photospheric lines, a collection of sharp emission
lines, and the broad emission lines of the NaI doublet. The sharp
emission lines are considered to be chromospheric lines.
