Abstract

A systematic study of the even-A germanium isotopes with mass 70 ≦ A ≦ 78 via the Se(d, 6Li) reaction has been performed at Ed = 45 MeV. The reaction products were momentum analysed and mass identified with a QMG/2 magnetic spectrograph and the accompanying focal-plane detector system. The main emphasis of this investigation was on the nature of the first excited 0+ states. The striking variation in strength from one isotope to the other already observed in the (p, t) reactions to the same final nuclei is also seen for the α-pickup reaction. Previously derived wave functions that assume the excited 0+2 states to be pure proton configuration states can also account for the present results.
