Abstract
The reactions22Ne(d, t)21Ne and22Ne(d, τ)21F have been investigated in a parallel experiment atE d=52MeV. Energy spectra of tritons andτ particles have been measured up to excitation energies of 18MeV in both21Ne and21F nuclei. Thel values could be determined, and spectroscopic factors have been obtained by a DWBA analysis of the measured angular distributions. Together with the results from a preceding\({}^{22}Ne(\vec d, \tau ){}^{21}F\) experiment, several spins could be determined in21F. From a comparison of the triton andτ particle spectra,T=3/2 states in21Ne could be identified and on this basis the new information on spins of21F states could be transferred to their analog states in21Ne. The completeT < andT > parts of the (2s, 1d) strengths could be observed. The 1p strength is highly fragmented. Of theT < part only 60% of the 1p1/2 and 40% of the lp3/2 strength could be found, but the totalT > part of the 1p strength could be localized. The spectroscopic results for positive parity states are in qualitatively good agreement with shell model predictions.
