The effects of breakup to singlet spin states on elastic scattering observables for the scNi(d, d) 5cNi reaction at 400 MeV is studied. The singlet breakup contribution to the elastic amplitude is estimated through an approximate two-step calculation, in which we exploit an adiabatic approximation and closure over the intermediate continuum states. The inclusion of the singlet channel coupling ...

Proton-proton correlations from spectator decays following 197 Au+ 197 Au collisions at 1000 AMeV have been measured with an highly efficient detector ho-doscope. The constructed correlation functions indicate a moderate expansion and low breakup densities similar to assumptions made in statistical multifrag-mentation models. In agreement with a volume breakup rather short time scales were dedu...

The pinch-off behavior of yield stress fluids is investigated using droplet and liquid-bridge breakup experiments. Contrary to expectations, the neck thinning behavior depends strongly on the way the breakup experiment is carried out. This nonuniversal behavior can be explained through an analysis of the thinning dynamics as well as the shapes of the fluid necks. Recent nonlocal models for the ...
