Using the (d, 3He) reactions on 9~ and 144Sm at 52MeV spins of deeply-bound hole states have been measured for the first time. In contrast to neutron pick-up reactions the shell model strength is exhausted which enables us to derive the If and 1 g spin-orbit splitting.
The reactions 22Ne (d,t)21Ne and 22Ne(d,t)2~F have been investigated in a parallel experiment at E~=52 MeV. Energy spectra of tritons and r particles have been measured up to excitation energies of 18 MeV in both ZtNe and 2tF nuclei. The l 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 22Ne(I],r)2aF experiment, several spins could be determined in 2~F. From a comparison of the triton and z particle spectra, T=3/2 states in 21Ne could be identified and on this basis the new information on spins of Z aF states could be transferred to their analog states in ZINc. The complete T< and 7-> parts of the (2s, ld) strengths could be observed. The l p strength is highly fragmented. Of the T< part only 601',i of the lp1;2 and 40~,] of the 1p3,2 strength could be found, but the total T> part of the lp strength could be localized. The spectroscopic results for positive parity states are in qualitatively good agreement with shell model predictions.
