In fact, in the first case an enhancement of the rate by some orders of magnitude is predicted for the case of coincidence between the released energy and the energy of an excited state. The investigation of neutrinoless \u03b2+\u03b2+ (2EC and EC\u03b2+) processes can refine the understanding of the contribution of right-handed currents to neutrinoless 2\u03b2\u2212 decay; therefore developments of experimental technique to search for \u03b2+\u03b2+ decays are strongly required in order to improve methodologies for future increased sensitivity. These setups have allowed us to obtain competitive results in these studies.<\/p>\n\n\n\n<p><a href=\"https:\/\/dama.web.roma2.infn.it\/?page_id=283\"><strong>Photos<\/strong><\/a>\u00a0of DAMA\/R&amp;D experiment can be found\u00a0<a href=\"https:\/\/dama.web.roma2.infn.it\/?page_id=283\">here<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The DAMA\/R&amp;D set-up is general purpose low background set-up used to test PMTs and detectors prototypes and to realize small scale experiments.
