34 //
35 // Description:
36 // Stores the statistical tensor describing the nuclear polarization
37 // (see Alder and Winther, "Electromagnetic Excitation" (1975),
38 // Appendix F).
39 //
40 // V.Ivanchenko left only polarization tensor and access methods
41 // in this class, also add operators
42 // this allows future implemention of polarized
43 // hadronic models with polarized initial and
44 // final states
