Pairing and quartetting are competing phenomena in nuclei. In the selfconjugate nuclei from the fp-shell, the competition between T=0 pairing (deuteron-like) and alpha clusterisation is predicted to be a_ected by the spin-orbit interaction. In order to probe the α structure of fp-shell nuclei, the nuclear break-up of 40Ca and 40Ar has been measured at GANIL. The α spectroscopic factors obtained for the N=Z nucleus and the N≠Z nuclei do not reflect any difference. This might be an indication that the tail of the wave function in not sensitive to nuclear asymmetry. Perspectives for probing the deuteron-like pairing (T=0) are given.
