Multiphonon vibrations at high angular momentum in 182 Os

Phys Rev Lett. 2003 Oct 31;91(18):182501. doi: 10.1103/PhysRevLett.91.182501. Epub 2003 Oct 30.

Abstract

Evidence is presented for multiphonon excitations based on a high-spin (25 Planck) intrinsic state in the deformed nucleus 182 Os. Angular momentum generation by this mode competes with collective rotation. The experimental data are compared with tilted-axis cranking calculations, supporting the vibrational interpretation. However, the lower experimental energies provide evidence that more complex interactions of states are playing a role.
