Abstract
Systems evolving according to effective non-Hermitian Hamiltonians are considered. To each eigenvalue of the effective Hamiltonian is associated two eigenstates [Formula preented] which evolve backward and forward in time, respectively. Adiabatic measurements on such systems are analyzed. The outcome of the adiabatic measurement of an observable A is the weak value [Formula preented] associated with the two-state vector [Formula preented]. The possibility of performing such measurements in a laboratory is discussed.
