The decay rate of neutrinoless double beta process is expected to give the first direct measure of the neutrino mass, if the corresponding nuclear matrix element can be reliably calculated [1]. A major complication in extracting the neutrino mass from the half-life of this decay is the uncertainty in the nuclear matrix element. There are certain experimental observable that may be placed to...
Nuclear Data evaluation is a very essential part of Experimental nuclear research. The Nuclear Structure and Decay Data Evaluation evaluation is a source to many new experiments and new ideas, besides the standardization of experimental data.
Mass A=139 data evaluation led to a new experiment for measuring the half life of 139Ba which had several past measurements not in agreement. The same...
The structure of nuclei around the line of stability with A~200 exhibits diverse excitation modes ranging from collective rotation, including decoupled and semi-decoupled bands, and isomeric states whose decay rates span a large range from enhanced to hindered in comparison with single-particle estimates. The evolution of collectivity and the gradual predominance of intrinsic excitations with...
The nuclear dipole polarizability - a second-order effect in Coulomb-excitation perturbation theory competing with the reorientation effect that varies with the shape of a nucleus and splitting of magnetic substates – governed by the dynamics of the giant dipole resonances has been investigated along with the effects of recently observed enhancement of photon strength functions at low...
Nuclear metastable states with half-lives longer than a few nanoseconds may be found in many nuclides in the nuclear landscape. With the increasing sensitivity of different measuring techniques, a number of new isomers are being discovered with various spectrometers at new accelerator facilities. These isomers provide a tool to study the different nuclear structure models. Furthermore, a wide...
