In this paper we present the beta -level mixing resonance (beta -LMR) method as a tool to measure the initial spin-orientation of exotic nuclear beams produced and oriented in a fragmentation reaction. Understanding this spin-orientation process is the key to allow studies of nuclear moments of nuclear states far from stability. The beta -LMR method is a unique tool, sensitive to both the spin-polarization and the spin-alignment component in the selected ensemble of fragment spins. In the paper we describe the formalism to extract this information from the experimental data and report on a first test experiment.
