In this talk I first give a short overview of antinuclei produsction in recent experiments at RHIC. Then I discuss the possibility of producing new types of nuclear systems by implanting an antibaryon into ordinary nuclei. The structure of nuclei containing one antiproton or antilambda is investigated within the framework of a relativistic mean-field model. Self-consistent calculations predict ...

We introduce spin projection methods in the shell model Monte Carlo approach and apply them to calculate the spin distribution of level densities for iron-region nuclei using the complete (pf+g9/2)shell. We compare the calculated distributions with the spin-cutoff model and extract an energydependent moment of inertia. For even-even nuclei and at low excitation energies, we observe a significan...

Saturation of low - energy antiproton annihilation on nuclei

Recent measurements of very low-energy (p L < 100 MeV/c) ¯ p annihilation on light nuclei reveal apparent suppression of annihilation upon increasing the atomic charge Z and mass number A. Using ¯ p-nucleus optical potentials V opt , fitted to ¯ p-atom energy-shifts and-widths, we resolve this suppression as due to the strong effective repulsion produced by the very absorptive V opt. The low-en...
