Abstract

The first measurement of γ rays from the Sn114(n,γ) reaction using cold neutrons, performed with an array of Ge detectors at the PF1B facility of the Institute Laue-Langevin in Grenoble, has provided the most accurate energy, Qβ=173(12) eV, of β- decay of the In115 ground state to the first excited state in Sn115. This is the lowest of all such energies in the known nuclear landscape. The accuracy of the neutron binding energy of Sn115 and the mass of Sn114 have been improved.
