“…The observed results were in good agreement with expectations from the previously reported decay chains of element 115 produced at the Dubna GasFilled Recoil Separator (DGFRS) [3]. In order to check an assumption that dubnium undergoes electron capture prior to the SF, separation of Group IV and V elements is required, which was the motivation for performing the second experiment.…”

“…Superheavy elements have been subject of an intense experimental activity over the past few decades [2][3][4]. Elements 108 (Hs) [5][6][7], 109 (Mt) [8][9][10], 110 (Ds) [11], 111 (Rg) [12], 112 [13][14][15], 113 [16], 114 [17][18][19][20], 115 [3], 116 [21][22][23], 117 [24] and 118 [25,23] have been observed in a series of experiments in Berkeley, GSI, Dubna and RIKEN.…”

We explore QED and many-body effects in superheavy elements up to Z = 173 using the multiconfiguration Dirac-Fock method. We study the effect of going beyond the average-level approximation on the determination of the ground state of element 140, and compare with the recent work of Pekka Pyykkö on the periodic table for super heavy elements [1]. We confirm that QED corrections are of the order of 1% on ionization energies. We show that the atomic number at which the 1s shell dives into the negative energy continuum is 173, and is not affected by the approximation employed to evaluate the electron-electron interaction.

“…Correspondingly, a high-resolution α-photon coincidence spectroscopy experiment was conducted to investigate decay chains supposedly originating from element 115 [16]. Here, we focus on details of the Ge-detector analysis, further Monte-Carlo simulations, and assessments of the hitherto available published data on the isotopes 287,288 115 [16][17][18].…”

Alpha-Photon Coincidence Spectroscopy Along Element 115 Decay ChainsRudolph, Dirk; Forsberg, Ulrika; Golubev, Pavel; Sarmiento Pico, Luis; Yakushev, A.; Andersson, L.-L.; Di Nitto, A.; Düllmann, Ch.E.; Gates, J.M.; Gregorich, K.E.; Gross, C.J.; Herzberg, R. Produced in the reaction48 Ca+ 243 Am, thirty correlated α-decay chains were observed in an experiment conducted at the GSI Helmholzzentrum für Schwerionenforschung, Darmstadt, Germany. The decay chains are basically consistent with previous findings and are considered to originate from isotopes of element 115 with mass numbers 287, 288, and 289. A set-up aiming specifically for high-resolution charged particle and photon coincidence spectroscopy was placed behind the gas-filled separator TASCA. For the first time, γ rays as well as X-ray candidates were observed in prompt coincidence with the α-decay chains of element 115.
