Abstract
Angular distributions of differential cross sections and vector analyzing powers were measured forl=0, 1 and 2 transitions induced by the\(^{26} Mg\left( {\overrightarrow d ,\tau } \right)^{25} Na\) reaction at 52 MeV. The following spins and parities of final states in25Na were deduced:Jπ=1/2+ (1.069 MeV), 3/2+ (2.202 MeV), 5/2+ (2.914 MeV), 1/2− (3.995 MeV) and 3/2− (5.190, 5.690, 6.549 and 7.603 MeV). The DWBA analysis of proton and neutron pick-up spectra obtained from a parallel measurement of the26Mg(d, τ)25Na and26Mg(d, t)25Mg reactions allows the identification ofT=3/2 analog states in25Mg. Interpretation in terms of the Nilsson model of energies and spectroscopic factors of the first 1/2− and 3/2− hole states observed in proton pick-up reactions from even 1d5/2- shell nuclei indicates a close correspondence of the final state deformations with those of the first excited 2+ states in the target nuclei.
