The Level Structure of ⁶⁹Ge

Structure of69Ge

“…The ground state of 69As was assigned a tentative J~=5/2 in the work of Muszynski and Mark [1] on the basis of its decay properties and nuclear systematics. The J~ assignments of 5/2-, 1/2-, 3/2 and 3/2-for these states, respectively, have been confirmed by nuclear reaction works [-2, 3, 8] and inbeam spectroscopy works [4,6,7]. The results of the present experiment on the ground state, 86.79, 232.73 and 374.1keV states in 69Ge, though more precise are in general agreement with those of Ref.…”

“…The J~ assignments of 5/2-, 1/2-, 3/2 and 3/2-for these states, respectively, have been confirmed by nuclear reaction works [-2, 3, 8] and inbeam spectroscopy works [4,6,7]. Subsequently, the state has been reported in several other works [3][4][5][6], with similar conclusions. The results of nuclear reaction works indicate that the ground state, 86.79 and 374.1 keV states in 69Ge contain substantial single neutron components of lf5/2, 2pl/2 and 2p3/2 orbitals, respectively, in their wave functions.…”

The level structure of69Ge

“…Low spin states of 69Ge have been studied through the /j-decay of 69As [1] and the reactions 69Ga(p, nT) [2], :~ d) [3], and ~~ ~) [4]. From the/J-decay 4 levels with an excitation energy <400 keV were established.…”

“…From the/J-decay 4 levels with an excitation energy <400 keV were established. The study of the (p, nT) reaction by [2] was carried out by measuring ?,-singles spectra. Levels with spin =<9/2 were established by means of energy differences and intensities.…”
