Spectroscopy of 10He

The mass of 10He has been measured with the double charge exchange reaction 10Be( 14C, 14O) 10He at E Lab = 334.4 MeV and a mass excess M.E. = 48.81 (7) MeV is obtained. It follows that 10He is particle unstable against 2 n- emission by S 2n = −1.07(7) MeV . Two excited states are observed: a broad...

Summary:The mass of 10He has been measured with the double charge exchange reaction 10Be( 14C, 14O) 10He at E Lab = 334.4 MeV and a mass excess M.E. = 48.81 (7) MeV is obtained. It follows that 10He is particle unstable against 2 n- emission by S 2n = −1.07(7) MeV . Two excited states are observed: a broad resonance at an excitation energy of E x = 3.24(20) MeV , and a strong resonance at E x = 6.80(7) MeV .
