Abstract. The superfluid liquid model with triplet pairing is applied to the analysis of the superdeformed bands in A ~ 130-150 region. A two-parameter expression for the 7-transitions energies allows a description, good in the A ~ 150 region and rough for the A ~ 130 nuclei, of the experimental data. The introduction of the third parameter gives considerable (especially in the A~ 130 region) improvement of quality of the description close to or within experimental uncertainties. In this superfluid liquid model the appearance of the superdeformed bands is a consequence of the nuclear matter properties, rather than a shell model feature.

“…At this bombarding energy the expected average value of angular momentum brought to the compound nucleus was about 78 ÿ, corresponding perfectly to the prediction in figure 43. Shortly thereafter an existence of similar long cascades of γrays has been demonstrated in 148 Gd [78], 149 Gd [79] and 151 Dy [80] as well as in the nuclei of 150 Gd and 151 Tb. The latter two nuclei were studied within the Strasbourg-UK collaboration (Liverpool, Manchester, Daresbury) with TESSA I at Daresbury [81].…”

This article overviews a long period of an important evolution in the nuclear structure research in Strasbourg Laboratories, focussed on tracking of the weaker and weaker experimental signals carrying the more and more important physics messages. In particular we address the research of signatures of the collective behaviour of the nucleus as suggested in the early works of Bohr, Mottelson and Rainwater-at high and very high angular momenta-as well as the competition between the collective and non-collective excitation modes. These ambitious goals were possible to achieve only by constructing powerful spectrometers and developing related detectors, electronics and data acquisition systems. The theoretical modelling developed in parallel, provided essential guidance when choosing the right experiments and optimising their realisation. Theory calculations were equally helpful in interpreting the results of experiments leading to a more complete understanding of the underlying physics. Moreover, thanks to the development of heavy ion accelerators, the Strasbourg centre was the place where crossed the ways of many experimenters from European countries both from the Western and from the Central part of Europe, the place of the gradual development of more and more sophisticated European gamma-spectrometers in collaboration with more and more laboratories from the increasing number of countries allowing for the frontier-level studies of the nuclear behaviour at very high angular momenta.

“…The very large deformation of that nucleus was confirmed by a measurement of the quadrupole moment [2]. Superdeformation was discovered in other nuclei of this region [3][4][5][6][7][8][9] as well as in other regions of the nuclear chart [10][11][12][13][14]. However, a lot of questions concerning the formation and decay of superdeformed states remain so far unsolved: for example in none of the k-Dedicated to Prof. Dr. P.

Superdeformed (SD) bands in152Dy,151Dy and151Tb have been populated via the 5n, 6n and 5np evaporation channels, respectively, with the33S+124Sn reaction at 160 and 170 MeV bombarding energies. Population intensities are in good agreement with existing data for SD bands in151, 152Dy and SD yrast band in151Tb. The excited twin SD band in151Tb with the same-transitions as the band in152Dy is populated about 5 times more strongly than by the 6n evaporation channel. This might be explained in terms of competition between proton and emission out of an intermediate, excited superdeformed configuration of152Dy
