In this work (p, d) reactions on 5RNi were studied, initiated by 24.6MeV polarised protons and leading to several final states in 57Ni. The cross sections and analysing powers obtained experimentally were compared with DWBA and cc calculations, confirming spin and parity assignments. Two-step transitions (p, p')(p', d') were found to contribute substantially to some of the transitions.NUCLEAR REACTIONS 5XNi(polarised p, d), (polarised p, d'), E = 24.6 MeV; measured a(Ed', e), A(Ed', 0); deduced J , R. DWBA, CRC calculations; two-step processes.

For pt.I see ibid., vol.15, no.2, p.181 (1989). Inelastic scattering of polarised protons (Ep=20.4, 24.6 MeV) by 60,64Ni, 86,88Sr, 110,112,114Cd, 115In and 116,118,120,122,124Sn has been investigated. Except for the case of 60Ni, only for the 21+ and 31- states could statistically reliable data be obtained. The data have been analysed with the DWBA employing a collective form factor. The agreement between experiment and theory is fairly good, although the experimental data tend to exhibit somewhat more structure than the theory predicts. For 60Ni also data for higher excited states have been obtained. These have been analysed with moderate success by coupled-channels calculations. The deformation parameters found for the Sn isotopes can be described in terms of the IBA model. Some suggestions for the applications of the IBA model in inelastic scattering are given.

We have studied the (p, d) reaction on 56Fe, initiated by a 24.6 MeV polarised proton beam. Cross sections and analysing powers were obtained for nine states in the final nucleus 55Fe. These were compared with DWBA and CRC calculations, confirming spin and parity assignments. As opposed to the situation in 58Ni(~, d) no large two-step contributions were necessary for obtaining agreement with calculations.NUCLEAR REACTIONS 56Fe(polarised p, d), (polarised p. d'), E = 24.6 MeV; measured o(Ed', e), A ( E d ' , e); deduced J , n. DWBA, CRC calculations; no important two-step reactions.
