// 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
