Measurement of the double-beta decay half-life of Nd-150 and search for neutrinoless decay modes with the NEMO-3 detector

The half-life for double-beta decay of Nd-150 has been measured by the NEMO-3 experiment at the Modane Underground Laboratory. Using 924.7 days of data recorded with 36.55 g of Nd-150, we measured the half-life for...

New find monazite-(Nd) in sediments of the Drahany Upland

Authigenic monazite-(Nd)was found in greywackes from the Protivanov Formation, Drahany Upland. Monazite forms irregular aggregates up to 150 micrometers in diameter. Monazite aggregates enclose a variety of detrital and authigenic m...

Excitation functions of proton-induced reactions on natural Nd in the 10-30 MeV energy range, and production of radionuclides relevant for double-beta decay

A preferred candidate for neutrinoless double-beta decay, (150)Nd, is present in natural neodymium at an abundance level of 5.64%. However, neodymium could be activated by cosmic rays during the period it spends on the Earth's surfa...

0 nu beta beta-decay nuclear matrix element for light and heavy neutrino mass mechanisms from deformed quasiparticle random-phase approximation calculations for Ge-76, Se-82, Te-130, Xe-136, and Nd

In this paper, with restored isospin symmetry, we evaluated the neutrinoless double-beta-decay nuclear matrix elements for Ge-76, Se-82, Te-130, Xe-136, and Nd-150 for both the light and heavy neutrino mass mechanisms using the defo...
