High-resolution inelastic-scattering measurements on 112Cd with polarized deuterons (20 MeV) and polarized protons (16 and 65 MeV) provide complete spectroscopic information. Transition moments are obtained from the angular distributions of the cross section and analyzing power in a coupled-channel reaction analysis. The results are compared with interacting boson model predictions aiming to describe intruder states, quadrupole-hexadecapole and quadrupole-octupole excitations.

The excitation spectrum of 41Ca up to the emission threshold has been investigated in a magnetic spectrograph study of the 41Ca(d,p) reaction at Ed = 20 MeV with polarized deuterons. From DWBA and CCBA data analyses, experimental strength distributions are obtained for single-particle configurations in 41Ca. These results are compared to quasiparticle RPA calculations. The radial dependence of the form factors is studied with respect to the excitation energy behaviour with major shell mixing. We find that in general the observed occupation respectively depopulation of the orbitals can be well accounted for by the theoretical model.

The -γ-ray spectrum emitted after thermal neutron capture in 31P was studied at the ILL high flux reactor with a pair spectrometer and an intrinsic Ge detector. A total of 212 transitions were assigned to the decay of 32P and 155 of these, representing 96.7% of the observed flux, were placed in a level scheme of 38 states. The neutron binding energy was determined as 7935.74 (16) keV. The densities of states observed in this reaction and in a recent (d, p) study are analyzed in the constant temperature Fermi-gas model. The primary E1 and M1 transition strengths in 32P are discussed and are compared to other sd-shell nuclei.

Neutron strength distributions of $^{41}\mathrm{Ca}$ have been obtained from a high resolution study of the $^{40}\mathrm{Ca}$(d\ensuremath{\rightarrow},p) reaction. They agree well with quasiparticle-phonon coupling calculations in a large configuration space including major shell mixing. We see no evidence of strong depopulation of closed shell orbitals.

Neutron pick-up measurements have identified the s12 and d32 holes states in 147Gd, 145Sm, and 143Nd. The results also locate the 12+ and 32+ members of the vf72×3− septuplet via their admixtures from these hole states. Additional energy perturbations of the septuplet result largely from a negative quadrupole moment of the octupole phonon, with a Z-dependence consistent with the microscopic structure of the 3− excitation in the N=82 nuclei.

The reaction 36S(d, p) has been studied at Ed = 20 MeV with enriched 36S using H2S gas targets and the Q3D magnetic spectrograph. We identify 35 excited states in 37S. Angular distributions for dσdΩ(θ) and Ay(θ) yield quantum numbers Jθ and spectroscopic factors for most of them. Comparison is made to the distribution of strength in 41Ca. From an additional (d,d′) experiment at Ed = 23 MeV we derive multipole moments for the 2+1 and 3−1, state in 36S.

Precise measurements of cross sections and complete sets of analyzing powers for the (d, α) reaction from 40Ca to the ground state 31+ and excited states 11+, 12+, 22+ of 38K at Ed = 20 MeV have been analyzed in a finite-range distorted-wave Born approximation, using full sd-shell-model wave functions and including a D-state amplitude for the deuteron clusters in the α-particle. Deuteron tensor potentials were included and the influence of two-step processes estimated. The results are compatible with the previous determination of D2 (4He) = − 0.19 ± 0.04 fm2 from the ground-state transition, which is found to be the most appropriate one for the determination of D-state effects.

For the Munich Q3D spectrograph a focal plane detector of 1.2 m length appropriate for polarized particle induced reactions has been developed. Improved position resolution of the resistive wire proportional detectors is achieved by additional readout of periodic cathode structures.

Precise measurements of a complete set of analyzing powers for the (d, t0), (d, 3He0) and (d, α0) reactions from 40Ca at Ed = 20 MeV have been analyzed in finite range DWBA. Deuteron tensor potentials and D-state amplitudes in a cluster expansion of the light fragments are included. From the data in the transfer peak region we obtain D2 (3H) = −0.20 ± 0.04 fm2, D2 (3He) = 0.25 ± 0.05 fm2 and D2 (4He) = −0.19 ± 0.04 fm2−
