We discuss recent work on Coulomb dissociation and an effective-range theory of low-lying electromagnetic strength of halo nuclei. We propose to study Coulomb dissociation of a halo nucleus bound by a zero-range potential as a homework problem. We study the transition from stripping to bound and unbound states and point out in this context that the Trojan-Horse method is a suitable tool to inve...

As shown in some talks [1] of this conference, statistical descriptions work very successfully for multihadron final states in nucleon-nucleon, nucleon-nucleus, and nucleus-nucleus collisions. In this approach the chemical equilibrium particle ratios are functions of temperature T and baryon chemical potential μB only . Recently GSI measured Au-Au and Ni-Ni collisions at 0.8 ∼ 2.0 GeV. Some mea...

Two examples, not connected at present, from author’s papers (Nuovo Cim., 1992, v.105A, p.77 [hep-th/0207210] and GRG, 1999, v.31, p.1431 [gr-qc/0207017]) are considered here in which a physical model has discrete symmetries and additional non-observable coordinates or parameters. Then it is possible to introduce some apparent continuous symmetries of the model for an observer which cannot know...
