“…Several new transitions were identified and assigned to the βγ and β-delayed neutron-γ (βnγ) decay branches of 86 Ge (T 1/2 =226(21) ms) and 86 As (T 1/2 =861(64) ms) [2].…”

“…The experimental technique was described in detail in Ref. [2]. In brief, the 86 Ge ions were produced in the proton-induced fission of 238 U and ionized to a charge state +1 in the Injector for Radioactive Ion Species 2 (IRIS2) ion source.…”

“…This is due to the fact that from this data it is not possible to disentangle the contributions to the 1115 keV transition from βn decay of 86 As and from β decay of 85 As (see Figure 1). Energies are given in keV, I β in %; Q-values and Sn stem from [4], half-life from [2] and Pn from [18]. Upper limits for I β were determined by assuming no decay to the g. Table II and Figure 7).…”

confidence: 99%

“…The most intense line in 86 Ge β decay, at 112 keV, was assigned to its βγ decay-branch on the basis of half-life considerations, ion-source chemistry and mass separation [2]. All the other transitions including those at 98, 119, 125 and 1965 keV visible in the βγ spectrum (see Figure 2), as well as those detected only with the help of an additional γ coincidence (see, e.g., Figures 3 and 4), were assigned to the same decay by means of βγγ coincidences.…”

The β decay properties of very neutron rich nuclei 86 Ge and 86 As were measured at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory. Spectroscopic information on new excited states in 86 As and in 86 Se was obtained and is interpreted within an advanced shell model approach. These calculations, previously explaining well the structure of 84 Ge and 85 Ge, are not able to reproduce all the experimentally-determined features of the measured level schemes of 86 As and 86 Se. The Gamow-Teller decay of 86 Ge and 86 As is also investigated in a shell-model framework. The fission yield for 86 Ge is discussed.

The evaluated experimental data are presented for 14 known nuclides of mass 87 (Ga, Ge, As, Se, Br, Kr, Rb, Sr, Y, Zr, Nb, Mo, Tc, Ru). New datasets have been added for 87 Ga, 87 Se, 87 Kr, 87 Rb, 87 Sr, 87 Nb, and 87 Tc.The observation of and new lifetime measurements for 87 As at the NSCL Coupled Cyclotron Facility and the Oak Ridge Isochronous Cyclotron at the HRIBF-ORNL Facility are included in the adopted levels for this isotope.The new evaluation also includes an isomeric level at unknown energy for 8 7 Tc, changes to the adopted levels f o r 8 7 N b b a s e d o n n e w l y p u b l i s h e d d a t a i n c l u d i n g a n e x t e n s i o n o f t h e h i g h s p i n l e v e l s a n d n e w l i f e t i m e m e a s u r e m e n t s , a n d n e w h e a v y i o n d a t a f o r 8 7 K r .

New excitation levels have been observed for the first time in 8 7 Se. New direct and precise measurement of atomic masses of 8 7 Tc, 8 7 Mo, 8 7 Nb, 8 7 Zr, 8 7 Mo and 8 7 Tc have greatly improved the Q value landscape in this mass region. This work supersedes the previous A=87 evaluation published in 2002He09, and Q values for all isotopes were updated to incorporate the mass evaluation in 2012Wa38.

Fragmentation data revealed new levels in 8 7 Tc, but the connection tothe ground state has yet to be clarified and excited levels have yet to be established for 8 7 As 8 7 Ga, and 8 7 Ge.The ground state spin and parity of 87 Br was changed to reflect new in-line measurements, but is tentative and more experimental work would be useful for further clarification.Cutoff Date: Literature available up to July 27, 2015 has been consulted.
