The present annual report of the Institute of Nuclear Physics (IKP) at the Kernforschungsanlage Jülich (KFA) covers the period from January to December 1980. It contains short descriptions of recent and current research work that has been carried out by the members of our institute or by guest groups frequently in close cooperation with scientists of the IKP. Most of the experimental studies make use of the variable energy beams of protons, deuterons, $^{3}$He- or alpha particles accelerated in our cyclotron JULIC. Neutron rich nuclei are investigated with the use of our large fission product separator JOSEF at the research reactor DIDO of the KFA. Also neutron capture studies are performed at this reactor. Again several of our staff members have carried out experiments in other laboratories in national and international cooperation with scientists at the ILL, CERN, and other institutions. Cooperation and international exchange is also characteristic for the scientific program of the members of the Institute for Theoretical Nuclear Physics of our IKP Department. Studies of giant resonance phenomena have been continued and new structures were observed at excitation energies of 17.5 and 21.3 MeV in $^{208}$Pb through scattering of 172 MeV $\alpha$-particles. Our large magnetic spectrograph "Big Karl" has served for an increasing number of high-resolution experiments. The study of 1$^{+}$ states in $^{208}$Pb is in progress and so is the spectroscopy of the $^{209}$Bi(d, $^{3}$He) $^{208}$Pb reactor for a group at the MPI Heidelberg. Part of the work on high-spin states aimed at the investigation of isomers in the odd-odd lanthanums and of the backbending in $^{182}$Os and the role of the i$-{13/2}$ neutron. The one-particle spectrum has been identified in $^{147}_{65}$Tb$_{82}$. The g-factor of the first excited 2$^{+}$ state of $^{100}$Zr has been measured in the context of a systematic investigation of the transitional nuclei with A $\backsimeq$ 100. The electronic K X ray isotope shifts of the stable lead isotopes have been studied in cooperation with the ISOLDE group and theorists from the IKP and ORNL. The study of the structure of the doubly closed $^{132}$Sn has been continued in a CERN-ISOLDE cooperation. Also here the experimental work was accompanied by detailed calculations made by our theorists. In addition to the investigation of the nuclear structures, mainly of collective states, the theory group has dealt with precritical phenomena and the generalized spin- and isospin- dependent interaction.
