A Mixed Session: Theory & Reactions & Structure
- Alexander Volya (Florida State University)
Recent advancements in quantum mechanics have challenged the classical understanding of decay processes, traditionally encapsulated by the exponential decay law. This presentation, based on our previous work [1], delves into the nonexponential decay regimes in open quantum systems, a domain governed by the continuum. The study illuminates the theoretical predictions and experimental...
The experimental evidence points to the existence, at short distances, of strongly correlated neutron-proton pairs much like they are in the deuteron or in free sca0ering processes. As it moves through the nuclear medium, a “bare” nucleon in the presence of the nucleon- nucleon interacton becomes “dressed” in a quasi-deuteron cloud, about 20% of the time [1]. A phenomenological analysis [2] of...
The even-even platinum isotopes from A = 190 − 198 are stable and have well-established B(E2,2+1 → 0+1 ) and derived τ(2+1 ) values measured via Coulomb excitation. These tran- sitional isotopes are gamma soft and show some evidence of triaxiality, exhibiting low-lying γ bands built on 2+2 states. In contrast, the mid-shell isotopes exhibit shape-coexistence, having level structures consistent...
The phenomenon of proton radioactivity, where the atomic nucleus is energetically unstable to the spontaneous emission of a proton is a crucial source of nuclear structure and mass- landscape information at, and beyond, the proton drip line. In addition, in contrast to alpha decay where the formation of an alpha particle close to the nuclear surface must be considered, the pre-existence of...
