[en] The angular distributions of the analysing power and the relative cross-sections for the elastic scattering of polarized ³He nuclei by ²H have been measured at incident ³He energies of 22.5, 24, 27, 30 and 33 MeV. The data, considered in terms of fitted Legendre polynomials, clearly show a structure near 30 MeV ³He energy which is more striking for odd L coefficients. In addition, our data, along with other data on the differential cross sections and on the analysing power for the scattering of polarized ²H, have been analysed for the phase shifts and mixing parameters in the S-matrix description. The phase shifts selected are compared with those from resonating-group theory calculations. The prominent residual differences were attributed to further resonances which involve the formation of ⁵Li nuclei at high excitation energy. Finally a level scheme is compared with the predictions of a multi-particle, multi-shell model calculation

[en] Angular distributions of the ³He analysing power and differential cross section were measured for the ²H(³He, ⁴He)¹H reaction at incident ³He lab energies of 27 and 33 MeV. Analysis of this and other data suggest the presence of a broad resonance, or resonances, around 28 MeV excitation in ⁵Li. The evidence for the dominant M-matrix elements involving a change in channel spin (i.e. the ΔS = -1 rule) is examined and also the question is investigated as to whether the data can be consistently explained without requiring tensor forces in the interaction.

[en] It has been established in numerous experimental studies that nuclear deformation plays an important role in heavy ion interactions. One of the most direct methods to investigate these effects is an application of polarized beams where the spin and thereby the mass alignment can be chosen at the source. The present experiment was performed with beams of tensor and vector polarized ²³Na interacting with the ²⁰⁸Pb target at 170 and 196 MeV to study the four analysing powers in quasi-elastic and reaction channels.

[en] The total cross section for the ²⁴Mg(α,n)²⁷Si reaction was determined in 10 keV energy steps from threshold to 13.1 MeV incident energy using the activation method. Variations observed in the cross section were interpreted using fluctuation theory with two notable results: firstly, that GAMMA, the average width of the observed fluctuations, does not vary at the rate expected over the energy range measured, and secondly that the majority of this reaction goes by a direct mechanism. This latter result was also found for the ²⁷Al(p,n)²⁷Si reaction after a reanalysis of published data. (Auth.)

[en] The data for differential cross sections and transverse tensor analysing powers in scattering of polarized ²³Na from ²⁰⁸Pb at 170 MeV were obtained for the ground, first and second excited states of ²³Na. The extracted data were analysed on the basis of the tidal symmetry model and the adiabatic approximation. By comparing these results with the exact coupled channel calculations and the measured data, the validity of tidal symmetry model is discussed. 4 figs., 1 tab., 8 refs. (author)

[en] The spin-spin correlation parameter T₁₁₁₁+Tsub(1-111) has been measured at 74⁰, 109⁰ and 128⁰ (c.m.) using a 12 MeV vector polarized deuteron beam and a polarized proton target. The analysis demonstrates that these data can be used to differentiate between the magnitudes of the quartet-doublet splitting employed in a number of models of d-p elastic scattering. (Auth.)

[en] Differential cross sections for the ¹²C(t, α)¹¹B reaction at 33 MeV have been measured and analysed for the transition to the 0.0, 2.125, 4.445, 5.021, 6.743, 7.286, 7.978 and 8.559 MeV states in ¹¹B. The results of CRC (coupled reaction channels) calculations are compared with DWBA (distorted wave Born approximation) and CCBA (coupled channels Born approximation) calculations for the single-step and two-step transitions respectively. The CRC calculations resulted in improved agreement with the experimental data for the strong transitions. (author)

[en] The differential cross section, vector analysing power and three components of the second-rank tensor analysing power were measured for quasi-elastic scattering of 170 MeV ²³Na from ²⁰⁸Pb. The data have been successfully interpreted in terms of the tidal symmetry model and the sign and magnitude of the observed polarisation effects are in good agreement with the known quadrupole moment of ²³Na.
