摘要
The level structure of Ru-114 has been investigated via the beta decay of very neutron-rich Tc-114 by means of Penning-trap-assisted gamma spectroscopy. The deduced beta-decay scheme suggests the existence of two beta-decaying states in Tc-114 with I-pi = 1(+) and I >= 4, with half-lives of l(1/2)(1(+)) = 90(20) ms and l(1/2)(I >= 4) = 100(20) ms, respectively. The Q(beta) value, which covers a possible mixture of two states, has been determined to be Q(beta) = 11 785(12) keV. The level energies in Ru-114 are compared with theory by using a microscopic Bohr Hamiltonian approach with the Sly4 version of the Skyrme interaction.
