“…The mass of 93 Pd yields a proton separation energy of 1180(390) keV for 94 Ag. If we now combine the one-proton decay data [5] with this proton separation energy and the mass of 93 Pd, an excitation energy of 6960(400) keV and a mass excess of −46370(170) keV is obtained for the (21 + ) isomer in agreement with the ex-(21 + ) 93 Pd + p 92 Rh + p + p (11 + ) 1548.6(14) [23] 1900(100) [6] 5780(30) [5] 94 Ag ( FIG. 3: (color online).…”

“…From the masses of 94 Ag and 92 Rh, a two-proton separation energy in 94 Ag is calculated, S 2p = −∆( 94 Ag) + ∆( 92 Rh) + 2∆( 1 H) = 4910(360) keV. If this two-proton separation energy is combined with the two-proton-decay data of the high-spin isomer in 94 Ag [E 2p = 1900(100) keV [6] and E x ( 92 Rh) = 1548.6(14) keV [23]], an excitation energy E x = 8360(370) keV is obtained for this isomeric state. When combined with the measured 92 Rh mass, the two-proton-decay Q value [6] gives a mass excess ∆ = −44970(100) keV for the high-spin isomer.…”

Mass Measurements and Implications for the Energy of the High-Spin Isomer inAg94

Nuclides in the vicinity of 94Ag have been studied with the Penning trap mass spectrometer JYFLTRAP at the Ion-Guide Isotope Separator On-Line. The masses of the two-proton-decay daughter 92Rh and the beta-decay daughter 94Pd of the high-spin isomer in 94Ag have been measured, and the masses of 93Pd and 94Ag have been deduced. When combined with the data from the one-proton- or two-proton-decay experiments, the results lead to contradictory mass excess values for the high-spin isomer in 94Ag, -46 370(170) or -44 970(100) keV, corresponding to excitation energies of 6960(400) or 8360(370) keV, respectively.

“…It seems to me that the data obtained recently on 92 Pd [19] might well be used for this purpose: While the 2n-evaporation channel has allowed the authors of Ref. [19] to produce 92 Pd through the 2n channel of 36 Ar + 58 Ni reactions, I presume that the same experimental data may allow them to improve the results on 93 Pd [13] and 92 Rh [14] by studying the 1n and pn channels, respectively.…”

“…The one and only case, where a state decays by one-proton [11] and two-proton [12] emission is 94m Ag (21 + ), recently observed at the GSI Online Mass Separator. The assignment of the proton and two-proton radioactivity was achieved by demanding coincidence with known γ-rays de-exciting high-spin states in the daughter nuclei 93 Pd [13] and 92 Rh [14], respectively. These results, in particular the conclusion on a large deformation of 94m Ag (21 + ), have led to considerable controversy.…”

Seven years ago, the GSI Online Mass Separator was decommissioned after 30 years of operation. The Golden Age of Jan Żylicz, celebrated at this Conference, is an adequate occasion to review the research performed at this facility. Its programme reached from nuclear-structure studies based on decay spectroscopy -the focus of this contribution -to investigations of nuclear shapes by means of laser spectroscopy all the way to experiments of astrophysical and fundamental-physics relevance. Reviewing this work I shall present my personal view on, firstly, examples of technical and scientific highlights and, secondly, the "humanistic" aspect of collaborating with many colleagues from abroad, including in particular Jan Żylicz and his associates from the University of Warsaw.

During the years 2005-2010 the double Penning trap mass spectrometer JYFLTRAP has been used to measure the masses of 90 ground and 8 isomeric states of neutron-deficient nuclides with a typical precision of better than 10 keV. The masses of 14 nuclides -84 Zr, 88,89 Tc, 90−92 Ru, 92−94 Rh, 94,95 Pd, 106,108,110 Sb -have been experimentally determined for the first time. This article gives an overview on these measurements and their impact on the modeling of the astrophysical rp-process.PACS. 21.10.Dr Binding energies and masses -26.30.Ca Explosive burning in accreting binary systems (novae, x-ray bursts)
