Structure of levels of the 160Gd nucleus

Lifetime measurements of low-spin negative-parity levels in Gd160

“…cindy calculations support the placement of both the 632.94-and 564.06-keV γ rays to a J π = 2 − state in agreement with Ref. [35]. The γ rays observed in this work from the 3 − level at 1691.68 keV agree with those proposed in Ref.…”

“…[35]. We confirm the placement of the 725.19 and 521.53 keV γ rays but are unable to calculate a lifetime due to low statistics.…”

“…Since the last evaluation of 160 Gd [34], three papers have made additions to the 160 Gd level structure using the (n, n γ) reaction [26,31,35]. This information has been considered along with the current results and is presented in Table I.…”

“…[31] (J π = 4 + ) and Ref. [35] (J π = 2 − ) can be addressed. The current data supports the 2 − assignment and experimental B(E1; 2 The collective quadrupole and octupole degrees of freedom were analyzed in 160 Gd using the well-known Generator Coordinate Method (GCM) with the Gogny D1S energy density function.…”
