Description
The spins of excited states produced in many nuclear reactions exhibit a degree
of alignment.The recoil-in-vacuum method extracts g-factors of shoft-lived (ps-
ns) nuclear states from the attenuation of angular distribution of decay
products from these aligned states caused by precession of the nuclear spin
about the unoriented electronic spins of ions which recoil from the target into
vacuum. This talk will outline published work demonstrating the potential of this
method when applied to states excited in radioactive beams by Coulomb
excitation. Recent experiments at the HRIBF Facility, ORNL, seeking to explore
accessible ranges of lifetime correlated with the element and charge state of
the recoiling ions will be described. Potential use at REX-ISOLDE will be urged.
