“…The level energies of 181 W in Table II were obtained from a least-squares fit to the E γ data from the current measurement. These energies agree with the adopted energies in ENSDF [59] within uncertainties with the exception of S n (see Sect. IV C).…”

“…Together with this analysis, the placement of transitions in the 181 W decay scheme was accomplished using previous previous information from ENSDF [59]. Owing to the complexity of the singles capture-γ spectrum, several expected γ rays often contribute to a much larger multiplet.…”

“…However, a broad spin window up to J = 11/2 , via direct and indirect population of both positive-and negative-parity states, is observed. Where available, spins and parities of levels as well as transition multipolarities and mixing ratios (δ γ ) reported in Table II were taken from ENSDF [59]; spins and parities could be verified from the present analysis up to an excitation energy of 610 keV (the established E c , see Sect. IV A) by comparison with the corresponding level populations.…”

“…Because of the random decay paths II: Experimental neutron-capture partial γ-ray production cross sections from the 180 W(n, γ) reaction with thermal neutrons. All spins, J, parities, π, and mixing ratios, δγ, are taken from the ENSDF adopted levels for 181 W [59] unless stated otherwise. Multipolarities, XL, in square brackets were assumed based on ∆J angular-momentum selection rules; other values were taken from ENSDF.…”

Radiative thermal neutron-capture cross sections for the 180 W(n, γ) reaction and determination of the neutron-separation energy Prompt thermal neutron-capture partial γ-ray production cross sections were measured for the first time for the 180 W(n, γ) reaction using a cold guided-neutron beam at the Budapest Research Reactor. Absolute 181 W γ-ray cross sections were internally standardized using well-known comparator γ-ray cross sections belonging to the other tungsten isotopes present in the 11.35%-enriched 180 W sample. Transitions were assigned to levels in 181 W based largely upon information available in the literature. The total radiative thermal neutron-capture cross section σ0 was determined from the sum of direct prompt γ-ray cross sections populating the ground state and a modeled contribution accounting for ground-state feeding from the quasi continuum. In this work, we find σ0 = 21.67 (77)

“…A slightly smaller energy, 26.02(10) keV, has been found for the second transition in our analysis of the electron spectrum (table 3). [15,23,[31][32][33][34]. The q value reported in the last column corresponds to the nucleus-recoil energy, E r, added to the α-particle kinetic energy, Eα, (q = Er + Eα).…”
