“…4. The comparatively long lifetime of this isomer explains why in the previous in-beam study [4] the 303 and 1065 keV 7-rays were found with almost isotropic angular distributions (see Subsect. The spectrum of prompt e-y coincidences does not contain the 303 keV 7-ray and this supports that this transition deexcites directly the isomer.…”

“…Furthermore several transitions assigned [4] to levels in 83Br including all those lines following the decay of the level at 3070 keV are observed in the third spectrum (lines at 303, 610 and 1065 keV). The isomeric behaviour of the 4 + level in 86Kr is indicated by the presence of the lines at 685 and I565 keV in the second spectrum.…”

“…The strongest lines belong to levels in 85Rb where in addition to the 514 keV 7-ray deexciting the known 9/2 + isomer (T1/z=l.01 gs) [8] also the first two members of the positive-parity cascade built on this isomer (779 and 1183 keV) [4] and the 350 keV 7-ray preceding these two transitions are easily identified.

Using methods of in-beam spectroscopy in connection with 35 MeV 7Li bombardment of 82Se targets four new isomers have been identified. They are observed in 83Br at 3070keV (T1/z=0.6+0.2gs), in SSRb at 2826keV (T1/z=12.5+0.6ns), in 85Kr at 1991 keV (T1/2 = 1.2• 1.o o.4 gs) and in 86Kr at 2250 keV (T1/2 =3.1 +0.6 ns). Spin and parity 19/2-have been assigned to the new isomer in 85Rb that is interpreted as the coupling of a P3/2 proton to the g9/2 two-neutron excitation of the N= 48 neutron system. Using the TDPAD method an upper limit for the g-factor of [gl<0.17 has been estimated for this isomer. The same two-neutron excitation is also believed to be responsible for the new isomer in S3Br. The new isomers in 85Kr and 86Kr are interpreted as configurations containing the two-proton excitation (f~2 ~, P~/~2) where in the isomeric 17/2 + level of 85Kr an additional g9/a neutron hole is involved.Nuclear Reactions: 82Se(YLi, ct2n)S3Br; 82Se(VLi, 4n)85Rb; 82Se(7Li, p3n)85Kr; 82Se(VLi, p2n)S6Kr; E=30, 35 MeV; measured Ey, a(E~, 0), 7-Y coin, e-y coin, p-y coin, y(t), y-ray linear polarization; 82Se(e, n)SSKr; E=13 21 MeV, measured Er, Iv, 7-7 coin, y(t). 8aBr, SSRb, 85Kr, 86Kr levels, deduced T1/2.

“…A special attention has been devoted to the 79Rb (N=42) nucleus which lies at the border of the well-deformed highly rotational region for N <42 [1~] and the moderately deformed y-soft region for N > 44 [5][6][7][8]. Several rotational bands have been identified and thoroughly investigated in V9Rb [2][3][4], the most intense being the positive-parity band built upon the 5/2 + ground state.…”

Excited states in SSRb have been studied via the S2Se(YLi, 4n) reaction by using in-beam y-ray spectroscopy. On the basis of new experimental data on coincidence relations, angular distributions and linear polarizations of the y-rays the yrast sequence has been extended up to a 33/2 + level at 7.1 MeV excitation energy. Using the DSA method mean lifetimes have been determined for 9 levels. Above the 21/2 + yrast state 5 fast M 1 transitions with B (M 1) > 0.3 W.u. have been identified. They are interpreted as transitions between recoupled states of the configuration ~zg9/2 V(g9/2)8+ 2 or -1 -1 7cg9/z(fs/2 P3/2)4+ v(g9/2)82.Nuclear Reaction: 82Se(YLi, 4n), E = 35 MeV; measured E~, o-(E~, 0), yy-coin., y-ray linear polarization, Doppler shift attenuation. 8SRb deduced levels, J, ~, ~, B()~).
