Systematics of l = 6 (d, p) transitions in N = 83 nuclei and a unified-model interpretation

Single-neutron energies outside136Xe

“…In this measurement, absolute cross sections for the (d,p) reaction are measured to allow for a quantitative comparison with other well-studied N = 82 isotones [14]. This was achieved by measuring the luminosity -the product of the beam intensity and the areal density of deuterons in the target -in the arrangement of Fig.…”

“…DWBA calculations were carried out using the finite-range code Ptolemy [23] with several sets of optical-model parameters [24]. Those used to deduce the spectroscopic factors of Table I and subsequent analysis are from [14]. For the deuteron boundstate wave function a Reid potential [25] was used.…”

“…These have been studied in the other stable N = 82 isotones (56 ≤ Z ≤ 62) via the (d,p) [14] and (α, 3 He) [5] reactions, the latter better matched for = 5 and 6 transfer than the (d,p) reaction. Significant fragmentation of the h 9/2 and i 13/2 strengths was seen due to mixing of the single-particle excitations with weak-coupling states of the same quantum numbers.…”

One-neutron transfer study of135Te and137Xe by particle-γcoincidence spectroscopy: TheAllmond1, Radford2, Pavan3 et al. 2012Phys. Rev. C

“…The . They are also known to mix with the 13/2 + , 3 − ⊗ 2f 7/2 multiplet member [10][11][12][13][14][15][16][17][18][19], which means the observed 13/2 + 1 energy is different from the unmixed single-neutron energy, ǫ s.p. (1i 13/2 ).…”

The level scheme of143Nd and a unified-model interpretation

“…Information on the properties of the energy levels has been obtained from (d, p) reaction measurements [1][2][3], measurements of the vector analysing power in the (d,p) reaction [4], inelastic deuteron scattering [2] and (n, 7) studies [5,6]. Recently Booth et al [7,9] reported the observation of two /=6 neutron transitions to J~=~+ states in the N=83 nuclei together with a unified-model interpretation. Extensive calculations of the nuclear levels in the N = 83 nuclei, based on the unified-model, have been done by Vanden Berghe et al [8].…”
