Laser-Induced Nuclear Orientation of 1 µs ^85mRb

Abstract

Laser-Induced Nuclear Orientation (LINO) [1] experiments employ intense laser optical pumping to orient unstable nuclei, and detect the subsequent angular anisotropy of the nuclear gamma ray emission. The profiles of anisotropy versus laser tuning yield atomic resonance frequencies from which nuclear moments and other structure parameters are derived. Prior to the present study, a number of experiments were performed using lamps as light sources,and were limited to nuclides with half-lives >1 s. LINO type experiments were also performed on-line at accelerator facilities [2,3] on nuclides whose lifetimes were in the range of milliseconds.
