Shell-model calculation of neutrinoless double- decay of Ge
R. A. Sen'kov, M. Horoi
In this article we present a more detailed version of our recent Rapid Communication [Phys. Rev. C 90, 051301(R) (2014)] where we calculate the nuclear matrix elements for neutrino…
Nuclear Level Density: Shell Model vs Mean Field
Roman Sen'kov, Vladimir Zelevinsky
The knowledge of the nuclear level density is necessary for understanding various reactions including those in the stellar environment. Usually the combinatorics of Fermi-gas plus…

Comment on ``Proton Polarization Shifts in Electronic and Muonic Hydrogen''
I. B. Khriplovich, R. A. Sen'kov
We demonstrate that criticisms concerning our work nucl-th/9704043, made in the recent preprint hep-ph/9903352, are unfounded. The improvements over our results claimed in hep-ph/9…
