Transfer reaction studies with spectrometers

The revival of transfer reaction studies benefited from the construction of the new generation large solid angle spectrometers, coupled to large γarrays. The recent results of γ-particle coincident measurements in 40Ca+96Zr and 40Ar+208Pb reactions demonstrate a strong interplay between single-particle and collective degrees of freedom that is pertinent to the reaction dynamics. The development of collectivity has been followed in odd Ar isotopes populated in the 40Ar+208Pb reaction through the excitation of the 11=2 states, understood as the coupling of single particle degrees of freedom to nuclear vibration quanta. Pair transfer modes is another important degree of freedom which is presently being studied with Prisma in inverse kinematics at energies far below the Coulomb barrier. First results from the 96Zr+40Ca reaction elucidate the role played by nucleon-nucleon correlation.
