“…In a radiochemical study [16] a half-life of 3.6 s for 112Ru was indirectly obtained, but it was later found to be related with the beta decay of the 1 + state of ll2Rh [17]. The recently reported half-life of 1.75 _+ 07 s for l~2Ru based on the time decay of the 327.0 keV ?-ray was measured at the IGISOL-facility [7].…”

Neutron-rich nuclides ~~ and ~2Ru produced in symmetric fission of 238U by 20 MeV protons have been studied at the IGISOL facility by means of/?-ray, y-ray and conversion electron spectroscopy. A total of 12 and 6 ytransitions were observed in the decays of 11~ and H2Ru, respectively. Multipolarities were determined for a few transitions. The beta decay half-life was determined to be 11.6__0.6s for H~ and 1.75+0.07s for ll2Ru.

“…e Same as a with mass formula of [26] method takes the advantage of symmetric fission induced by charged particles [49] allowing to optimize the product mass distribution by the proper choice of the target-projectile combination. Protoninduced fission of 238U has proven to be a promising source of neutron-rich isotopes in the region around Z=45 [40,50,51]. Figure 7 compares three predictions (the revised version of the gross theory, the TDA calculation and the QRPA calculation) with experimental half-lives of the most neutron-rich isotopes in this mass region.…”

Beta decay properties of nuclei far from stability are of decisive importance for the understanding of the element synthesis in the universe and the determination of the age of the universe by means of cosmochronometers. A new large scale microscopic calculation of/?--decay half-lives up to the neutron drip line is presented. This new approach uses the proton-neutron quasiparticle random phase approximation with a Gamow-Teller residual interaction.

“…This facility has proven to be very successful in search of new neutron rich isotopes during the last few years. Since 1986 several earlier unknown neutron-rich isotopes with A= 110-118 have been discovered [2][3][4][5][6]. Prior to this work the heaviest Pd isotope, whose decay was studied together with l~4pd and ~6Pd, was ~lsPd [5].…”

In this paper we wish to report the first direct observations of the beta decays of ll7pd and of a new isotope 119pd. The measured fl-half-life is 4.3 _+ 0.3 s for ~lTPd. For ~gPd, the existence of two beta-decaying states with the same half-life but of opposite parity cannot be excluded. The measured half-life for ~gPd is 0.92_+0.13 s. The observed beta half-lifes are in good agreement with the QRPA predictions. The observed level structure of l~7Ag and ~19Ag are discussed in the frame of the level systematics of the known odd Ag isotopes closer to stability.
