Abstract: The structure of the N=Z nuclei Zn-60, Ga-62, Ge-64 and Kr-72 has been investigated at GASP spectrometer through the S-32 + Ca-40 and Ca-40 + Ca-40 reactions at 140 and 160 MeV, respectively, using reaction channel selection with the ISIS Si-ball. The high spin states of such nuclei have been investigated searching for the four quasi-particle g(9/2) alignment. TRS calculations have been performed for the N=36, 38 and 40 Kr isotopes. In the case of Kr-72 th, four quasi-particle g(9/2) alignment is observed to be significantly delayed in rotational frequency with respect to the heavier Kr isotopes. Such a delay contradicts the predictions of mean field calculations and mag; be interpreted as the first sign of additional correlations in the...
