Penning-trap-assisted study of excitations in Br88 populated in β decay of Se88Czerwiński1, Sieja2, Rza̧ca‐Urban3 et al. 2017Phys. Rev. C74102View full textAdd to dashboardCite

“…[13] authors estimated β feeding to the ground-state of the 88 Br nucleus as no more than 38%. Later Lin et al reported a value of 20.5% [16], while in a recent compilation [7] an upper limit of 3% only is given. This situation requires clarification.…”

“…In the study of 235 U fission induced by cold neutrons [2] we proposed a spin and parity (1 − ) for the ground state of 88 Br, changing the (2 − ) assignment adopted in the compilation [7]. We also reported seven low-energy, low-spin levels interpreted as members of the πp 3/2 ν(d 5/2 ) 3 and πf −1 5/2 ν(d 5/2 ) 3 multiplets.…”

“…One should also firmly determine the spin and parity of the ground-state of 88 Br and remove doubts about its feeding through the β decay of 88 Se [7].…”

Total absorption γ -ray spectroscopy of the β -delayed neutron emitters Br87 , Br

“…We present 26 nucleus, and moderate neutron emission probability P n 37 as can be observed in Table I, showing decay parameters 38 taken from the ENSDF data base [1][2][3]. 10.281(8) 6.828 (10) The three aforementioned topics of research benefit experiments and calculations.…”

Triaxiality of neutron-rich Ge84,86,88 from low-energy nuclear spectra

“…It maintains a rather high value at N = 58 before it significantly drops at the onset of collectivity at N = 60. For Sr [50][51][52][53][54]56], Kr [50][51][52][53]56,57], and Se [49,57,59] isotopes, no such peaking of the 2 + 1 energies is found, but rather a flat behavior up to N = 58. Nevertheless, a slight increase in the 2 + 1 energy at N = 56 is observed for 92 Kr and 88 Ge (this work).…”
