“…The decay patterns to the 7/2 + , 9/2 + , and 11/2 + members of the 1/2 + ͓411͔ band, and the very good agreement with the level energies predicted based on a rotational parameter of 13.6 keV extracted from the 5/2 + -3/2 + energy difference, support the assignment of these levels as the 7/2 + , 9/2 + , and 11/2 + members of the 3/2 + ͓411͔ band tentatively assigned in Ref. [8]. Also shown is the extension of the 5/2 + ͓402͔ band to 17/2 + level based on M1/E2 in-band transitions, and the assignment of the 21/2 − band member of the 9/2 − ͓514͔ band.…”

Rotational bands in 175 Lu have been extended through investigation with the ͑n, nЈ␥͒ reaction. Spallation neutrons bombarded Lu samples, and the resulting ␥ rays were detected in a large-scale Compton-suppressed Ge detector array. Prompt-and delayed-␥␥ coincidences have been used to extend the 5/2 + ͓402͔ band to spin 17/2, the 3/2 + ͓411͔ band to spin 11/2, the 1/2 + ͓411͔ band to spin 15/2, and the 1/2 − ͓541͔ and 9/2 − ͓514͔ bands to spin 21/2. A new band, based on the 7/2 − ͓523͔ configuration, is tentatively assigned from its bandhead to spin 13/2. The three-quasiparticle K = 19/2 + isomer is confirmed and its half-life determined to be 984± 13͑stat. ͒ ±30͑sys. ͒ s, in agreement with previous results.

“…1, displays transitions that are emitted 150-750 ns before the 353-keV transition, i.e., these ␥ rays feed levels located above the 353-keV isomeric level. Most of the ␥ rays have been placed previously [7,8] in the 175 Lu level scheme. Some additional transitions are observed, and from Fig.…”

“…3, 5). Moreover, the present work has confirmed an energy level at 371 suggested by WI~TZR et al [7] as the head of a rotational band 1-/2 [541]. This eonfirmation is due to observing two new gamma transitions of energy 18 and 28.5 keV which can depopulate this state beside the 144 keV transition feeding it.…”

“…It should be pointed out that the 514.9 keV energy level suggested by JOHXr~SEr~ et al [6] from gamma spectroscopy and observed later by WINT~.R et al [7] from nuclear reaction has been supported on basis of 161/353 keV r (Figs. 3, 5).…”

Eleven gamma-ray transitions have been identified in 175Lu, by pefforming singles, prompt ~--~ coincidenee and delayed ~--~ coincidence measurements using Ge(Li), hyper pure Ge and NaI (TI) detectors. Two of these transitions (18 and 28.5 keV) have been observed for the first time and ate of value in supporting a recently reported energy level at 371 keV.Energy levels of rotational bands, 1-/2 [541]; 5+/2 [402] and 7+/2 [404] have been fitted using the angular momentum expansion. The required parameters ate given. The previously doubted spins 15-/2 (1137 keV) and the 21-/2 (1078 keV) in the band 1-/2 [541] have been theoretieally eonfirmed while an experimental energy state at 845 keV of doubted spin 13+/2 could be reasonably fitted to the 5+/2 [402] rotational band.
