Possible experimental measure theory for the XXX-Heisenberg chain.
Raising and lowering operators for the XXX-Heisenberg chain are derived explicitly; as a result the dipole moment operator is established. Based on the dipole transition mechanism in an external time-dependent magnetic field, we propose a possible experimental measure theory to detect the energy spectrum of the spin chain.
