“…Table 7). A shell model calculation of the 62Zn nucleus has been performed [1] in the frame work of the stretch scheme [27] (involving quartet structure): it gives the 6[ level at around 6.5 MeV excitation that excludes a possible identification with the 3,707 keV level. Very probably the compound nucleus reactions used to …”

“…The neutron deficient 62Zn nucleus has previously been studied by various transfert reactions: (160, 12C) [1], (p, t) [2][3][4][5], (3He, n) [6,7] and (6Li, d) [8] reactions, and J~ assignments up to 4 + have been deduced principally from the DWBA analysis of the (p, t) angular distributions. A few decay 7-rays were also known from the 63Cu(p, 2n7) reaction [4] (assigned from the relative pattern of the excitation function).…”

“…However, a selective population has been observed [8], and also for the 14~ 12C)144Nd reaction [9] involving states in 144Nd at excitation energies of ,~ 8 MeV. The clustering of extra-core protons and neutrons into an e particle on the surface of the core has been considered successfully in the rotor model of quartets [-10] in order to interprete the spectra obtained from a-transfer reactions in light and medium nuclei [11,12].…”

“…Par exemple en surface des noyaux, beaucoup d'orbites ne sont pas occupées et les restrictions du principe de Pauli sont moins sévères. On pense donc que la surface est riche en agrégats a. Encore faut-il que le mécanisme de transfert ait un caractère fortement sélectif qui alimente peu d'états excités des produits résiduels, de façon à voir apparaître nettement les niveaux d'énergie dans les spectres, comme cela est nettement montré [49] dans certains transferts (160, 12C) OU (160, J'insisterai un peu sur ces effets de sélectivité car ils constituent une réponse à ceux qui pensaient que l'utilisation de projectiles complexes conduirait à un mélange tellement compliqué d'états finaux qu'aucun renseignement de structure ne pourrait être fourni. Brink [19] a récemment discuté cette question de la sélection de population d'états individuels, en termes de conservation de vitesse de la particule transférée.…”
