GSI scientific report 1996

1996 was again a very productive year at GSI with many remarkable advances in the experimental and technical programme. The most spectacular result came once more from the field of super-heavy elements. On February 9, 1996, the first nucleus of element 112 or, more precisely, of isotope "2"7"7112 could be detected by the SHIP-group at the UNILAC. Another remarkable success in the field of nuclear structure physics was achieved at the fragment separator. With the first identification of "4"5Fe and "4"9Ni with an isospin-value of T_Z=-7/2, a new record was reached on the proton-rich side of isotopes. A further highlight in last year's programme was the first observation of low-lying pionic states in Pb. This experimental was also performed at the fragment separator. It ended a long-standing search for deeply-bound pionic states in heavy atoms at many laboratories worldwide and opened a new field of high-resolution spectroscopy with access to numerous questions relating to the pion-nucleus interaction and also to the nuclear density distribution. The Report contains many other - in total 140 - contributions from last year's research in the fields of nuclear and atomic physics, plasma physics, materials research, biophysics, accelerator technology and detector instrumentation.
