HYPATIA will extend current capabilities of in-beam γ-ray spectroscopy experiments currently carried out with DALI2⁺. The following is a list of some of the experimental methods where in-beam γ-ray spectroscopy is a crucial tool and all of these would benefit greatly from the HYPATIA array.

Some of the observables are listed in parenthesis.

• Two-step fragmentation reactions (transition energies, level scheme, E_x(2⁺), E_x(4⁺))
• Coulomb excitation (firm J^π = 2⁺ assignment, E_x(2⁺), B(E2))
• Few-nucleon removal reactions (level scheme, l-transfer, spectroscopic factors)
• Inelastic proton scattering (Mn/Mp, E_x(2⁺), E_x(4⁺), J assignments)
• Recoil distance Doppler shift (RDDS) (lifetimes, B(E2))
• Doppler shift attenuation method (DSAM) (lifetimes, B(E2))
• Recoil shadow method (lifetimes, B(E2))
