The decay of oriented 147Gd

Occupancy of single-proton orbitals in148Gd

“…3 can be associated with the previously known 755.1-keV level and supports its earlier d3/2 assignment [24]. The/i = 2 angular distribution for the 758-keV level in Fig.…”

“…3 is not consistent with l = 2, and no significant g9/2 strength is expected in this region. A state at 1244.4 keV with negative parity has been assigned J~=7/2-by Shastry et al [25], 11/2-by Kracikova et al [24], and 9/2-or 11/2-by Grigoriev et al [23]. Our level at 1243 keV has an angular distribution that could be consistent with l=4 or 1=5.…”

“…A level at 861.7 keV has been assigned J'= 5/2 + by Kracikova et al [24], and J'=7/2 + by Shastry et al [25]. However, the three peaks at 864, 993, and 1689 keV have reasonably convincing l=2 angular distributions.…”

“…The level structure of 147Eu has been studied by v-ray spectroscopy techniques with K-capture decay of 147Gd [23][24][25], and by in-beam spectroscopy with the (p, x n) [26,27] and (HI, xn) [28] reactions. The early experiments established J~= 5/2 +, 7/2 +, and 11/2-, respectively, for the ground and first two excited states.…”

Low-temperature nuclear orientation: Possibilities, results, perspectives

“…(4,5) that the separate values of B,x(n) have to be determined from the experimental anisotropies for pure transitions and the values of U;~(n) have to be calculated using the existent decay scheme. For n=g, we have…”
