The reaction l~ was investigated with high resolution (5 keV) at the Munich MP tandem using the Q 3 D spectrograph in conjunction with the precision time-of-flight system. The ground state Q-value was determined as Q = 3,684.5_+ 1 keV. Proton spectra were measured at 7 angles in the range of 6.1~ ~ 19 levels could be identified in the excitation energy range 0-730 keV. Transferred /-values and spectroscopic factors of these levels were derived with the aid of DWBA calculations.

“…4.3). The size of the quasi particle amplitudes derived from (d, p) studies [49] indicates that the odd neutrons in neutron deficient Ba nuclei are strongly hole like. In this case, the observed A I= 1 character of the favoured high spin bands gives indirect evidence for prolate deformation, the existence of parallel A I=2 bands for triaxial deformation [4,5].…”

Isotope shifts and hyperfine structure of the BaI resonance-line (2 = 553.6 nm) have been measured by dye laser induced resonance fluorescence on an atomic beam for 135m, 129g~ 129m. 126Ba thus extending previous high resolution measurements of neutron deficient Ba nuclides (N < 82). The experimental results, now available for 16 Ba isotopes and isomers with A=14(~126, are used to deduce differences of rms charge radii, magnetic dipole and electric quadrupole moments. While the groundstates display a pronounced odd-even staggering the h 11/2 isomers 135'~Ba and 133tuBa show a decreased staggering. Conspicuously the isomer shift of the g 7/2 + isomer ~29mBa proves to be negative. The nuclear structure information is discussed in the context of gammaspectroscopic studies of transitional nuclei with 50

Angular distributions of single nucleon transfer reactions populating single particle states in the reactions 138Ba(14C, 15N)137Cs and 138Ba(14C, 13C)139Ba have been studied. The shapes of the angular distributions show differences for different final configurations. Using the reaction asymmetry it is possible to describe these differences consistently for all transitions by a spin-orbit potential. The polarisation of the outgoing fragments is discussed and its dependence on final configurations is explained. The spin-orbit potentials deduced from the reaction asymmetry are large, as compared to predictions of folding potentials. They are, however, consistent with measurements of spin-flip probabilities. The origin of the L-S interaction is to be found in coupling effects of second order in the heavy ion reaction. I. MotivationRecent studies of direct reactions with heavy ions have shown that there are various observable effects connected with the spins of the interacting nuclei [1][2][3]. The most obvious effects, known from work with light particles, are related to the polarisation of reaction products produced in reactions and to analysing powers in reactions induced by polarised projectiles [4]. Polarisation and non-vanishing analysing powers can be produced by the vector coupling of angular momenta and spins in a surface reaction where only particular coupling schemes are strongly favoured. The clearest case for this circumstance can be found in the polarisation of final spins in Coulomb excitation [5]. This dynamic polarisation can be produced in any direct reaction in a one step interaction. The notion of an interaction potential containing the scalar product of orbital angular momentum and spin, L-S, is the second alternative. The L.S interaction can be due to the primary spin dependence of the nucleon-nucleon interaction [6]. The interplay of the dynamical polarisation with this L.S interaction produces a great variety of phenomena arising from the spin degrees of freedom in nuclear reactions (see for example [4]). The first studies of the spin dependent interactions of heavy ions [7][8][9][10] have shown that strong effects are observed, which, if attributed to an L.S interaction, cannot be traced back to the spin dependence of the nucleon-nucleon interaction. Models for the L.S interaction of heavy ions [11][12][13], where the nucleon-nucleon interaction is folded with the nuclear densities, tend to give L.S potentials whose strength is generally a factor 10-100 too small. It was realised recently that different channel couplings due to transfer reactions and inelastic excitations can contribute in second order to the polarisation and effectively be responsible for the spin dependent interactions [14][15][16]. The case with heavy ions is rather interesting because it offers possibilities to study different origins of the spin dependent interactions. The present work presents data on reaction asymmetries (introduced in [2,9]) for 15N
