Public Member Functions | |
| CSF2 (const DiracSpinor &a, const DiracSpinor &b) | |
| DiracSpinor::Index | state (std::size_t i) const |
| int | parity () const |
| Parity of the CSF, +/-1. | |
| std::string | config (bool relativistic=false) const |
| Single-particle configuration as a string, in relativistic or non-rel form. | |
Static Public Member Functions | |
| static int | num_different (const CSF2 &A, const CSF2 &B) |
| Returns number of different orbitals between two CSFs. | |
| static std::array< DiracSpinor::Index, 2 > | diff_1_na (const CSF2 &V, const CSF2 &X) |
| returns different orbitals, for case where CSFs differ by 1. i.e., returns {n,a} where |V> = |X_a^n> (i.e., V has n, but not a) | |
| static DiracSpinor::Index | same_1_j (const CSF2 &A, const CSF2 &B) |
| Returns the state in A and B that is the same (assumes A and B differ by 1) | |
