Probing pre-formed alpha particles in the ground state of nuclei
In this Letter, we report on alpha particle emission through the nuclear
break-up in the reaction 40Ca on a 40Ca target at 50A MeV. It is observed that,
similarly to nucleons, alpha particles can be emitted to the continuum with
very specific angular distribution during the reaction. The alpha particle
properties can be understood as resulting from an alpha cluster in the daughter
nucleus that is perturbed by the short range nuclear attraction of the
collision partner and emitted. A time-dependent theory that describe the alpha
particle wave-function evolution is able to reproduce qualitatively the
observed angular distribution. This mechanism offers new possibilities to study
alpha particle properties in the nuclear medium.Comment: 4 pages, 3 figure

Direct evidence of transfer with weakly bound isotopes of He near the Coulomb barrier and implications of fusion
NESTERPartial residue cross sections for fusion and transfer have been measured from the intensities of characteristic gamma-rays for the He + Cu systems at energies near the Coulomb barrier (Vb)
Probing the 6He halo structure with elastic and inelastic proton scattering
Proton elastic scattering and inelastic scattering to the first excited state
of 6He have been measured over a wide angular range using a 40.9A MeV 6He beam.
The data have been analyzed with a fully microscopic model of proton-nucleus
scattering using 6He wave functions generated from large space shell model
calculations. The inelastic scattering data show a remarkable sensitivity to
the halo structure of 6He.Comment: 9 pages, 3 figures. RevTeX. Replaced figure 3 with updated figur
