Nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) are supremely important techniques with numerous applications in almost all branches of science. However, until recently, NMR methodology was limited by the time constant T1 for the decay of nuclear spin magnetization through contact with the thermal molecular environment. Long-lived states, which are correlated quantum state...

Recent progress to treat clustering in nuclear systems has an impact different branches of theory. Numerical methods as well many-body theory (Green-function methods) have been worked out describe few-body clusters a environment where medium effects, particular the antisymmetrization wave function (Pauli blocking) are relevance. Nuclear structure (Hoyle – like states), reactions, and consequenc...

We analyze effects of the hyperfine interaction on electric dipole spin resonance when the amplitude of the quantum-dot motion becomes comparable or larger than the quantum dot's size. Away from the well-known small-drive regime, the important role played by transverse nuclear fluctuations leads to a Gaussian decay with characteristic dependence on drive strength and detuning. A characterizatio...

Reaction measurements on fission products are being planned at both Argonne National Lab and the Facility for Rare Isotope Beams. These indirect experiments produce specific short-lived nuclei via beta decay, subsequent neutron gamma emission studied. Some initial found a surprising overabundance of emission, which theory has yet to explain. To remedy this, we developing an integrated nuclear d...

Abstract A survey of nuclear structure results obtained along $$\alpha $$ α -decay chains stemming from isotopes element 114, Fl, and 115, Mc, is presented. Measures taken to ensure a reliable hand-over spectroscopy output theory are outlined. Possible links between decay starting 117, Ts, commented on. The e...

Advances in statistical learning theory present the opportunity to develop statistical models of quantum many-body systems exhibiting remarkable predictive power. The potential of such “theory-thin” approaches is illustrated with the application of Support Vector Machines (SVMs) to global prediction of nuclear properties as functions of proton and neutron numbers Z and N across the nuclidic cha...

The nuclear K–shell electron–capture (EC) and positron (β) decay constants, λEC and λβ+ of H–like Pr and He–like Pr ions, measured recently in the ESR ion storage ring at GSI, were calculated using standard weak interaction theory. The calculated ratios R = λEC/λβ+ of the decay constants agree with the experimental values within an accuracy better than 3%. The anomalous experimental value of th...
