Evolution of single-particle strength in neutron-rich $^{71}$Cu

Abstract : The strength functions of the πf5/2πf5/2, πp3/2πp3/2 and πf7/2πf7/2 orbitals in neutron-rich 71Cu were obtained in a 72Zn(d,3He)71Cu proton pick-up reaction in inverse kinematics using a radioactive beam of 72Zn at 38 MeV/u. A dedicated set-up was developed to overcome the experimental challenges posed by the low cross section of the reaction and the low energy of the outgoing 3He particles. The excitation-energy spectrum was reconstructed and spectroscopic factors were obtained after analysis of the angular distributions with the finite-range Distorted-Wave Born Approximation (DWBA). The results show that unlike for the πf5/2πf5/2 orbital and contrary to earlier interpretation, the πf7/2πf7/2 single-particle strength distribution is not appreciably affected by the addition of neutrons beyond N=40N=40.
