These E191800100024 values are obtained by combining two results from E191800100025 RIKEN and GSI. E191800100026 (108-HS-267,,A) E191800100027 9.6 to 10.0 MeV alphas with T1/2=52+13-8 msec (g.s.) E191800100028 and 0.80+3.8-0.37 sec (isomer) measured. These value E191800100029 is obtained by combining two results from RIKEN and E191800100030 GSI.
