¹⁵⁰Nd

The use of ¹⁵⁰Nd as double beta decay source in the future SuperNEMO experiment is under study. ¹⁵⁰Nd has a high Q-value (3.367 MeV) that makes it a very interesting isotope for several reasons:

• it has a highly favorable leptonic phase space compared to other double beta decay emitters (¹⁰⁰Mo, ⁸²Se, ⁷⁶Ge...)
• the expected background from ²¹⁴Bi (3.27 MeV, radon) will have less impact in the energy region of interest for neutrinoless double beta decay
• it seems possible to enrich significant amount of ¹⁵⁰Nd within reasonable time using some dedicated technology
