Difference between stable and exotic nuclei: medium polarization effects

The bare NN-potential, parametrized so as to reproduce the nuclear phase shifts leads to a sizable Cooper pair binding energy in nuclei along the stability valley. It is a much debated matter whether this value accounts for the "empirical" value of the pairing gap or whether a similarly important contribution arises from the exchange of collective vibrations between Cooper pair partners. In keeping with the fact that two-particle transfer reactions are the specific probe of pairing in nuclei, and that exotic halo nuclei like 11Li are extremely polarizable, we find that the recent studied reaction, namely 11Li+p -> 9Li+t, provides direct evidence of phonon mediated pairing in nuclei

Solid-phase synthesis of cyclic sulfonamides employing a ring-closing metathesis-cleavage strategy

Ring-closing olefin metathesis using the Grubbs catalyst was applied to the cyclisative release of resin-bound sulfonamides. Flexible linkers apparently facilitated the cyclisation-leavage, allowing a number of novel cyclic sulfonamides to be prepared in good yields using catalytic amounts of the Grubbs catalyst
