Abstract

The triple α-decay chain Ba114→Xe110→Te106→Sn102 has been directly observed for the first time, following the Ni58(Ni58,2n) reaction. Implantation of Ba114 nuclei into a double-sided silicon-strip detector has allowed their α decays to be correlated in position and time with the α decays of the daughter (Xe110) and granddaughter (Te106) nuclei. In total, 17 events have been assigned to the Ba114→Xe110→Te106→Sn102 triple α-decay chain. The energy of the Ba114 α decay has been measured to be Eα=3480(20) keV, which is 70 keV higher than the previously measured value, and the half-life of Ba114 has been measured with improved accuracy, to be 380-110+190 ms. A revised QC12 value of 19 035(45) keV for Ba114 is presented.
