Abstract

The ¹⁶O(⁶Li, d)²⁰Ne reaction has been studied at bombarding energies of 20, 32 and 38 MeV. The α-particle spectroscopic strengths have been extracted for levels up to 12.15 MeV in excitation. Nondirect processes appear to contribute significantly to all levels at 20 MeV and to high spin levels (6⁺ and 8⁺) at 32 MeV. Strengths extracted for members of the ground state band assuming (sd)⁴ transfer are unequal at both 32 and 38 MeV, in marked contrast to theoretical predictions. To explain this, particle-hole correlations in ¹⁶O(g.s.), inelastic channel coupling in the reaction and perhaps other effects as well, have to be considered. Strengths extracted for members of excited bands and α-decay reduced widths compare poorly with each other and with simple SU(3) predictions.

Cluster structure of 20Ne: Evidence for D<inf>3h</inf> symmetry
2021, Nuclear Physics A
We study the cluster structure of ²⁰Ne and show that the available experimental data can be well described by a bi-pyramidal structure with $D_{3 h}$ symmetry. Strong evidence for the occurrence of this symmetry comes from the observation of all nine expected vibrational modes (3 singly degenerate and 3 doubly degenerate) and of six (singly degenerate) double vibrational modes. ²⁰Ne appears to be another example of the simplicity in complexity program, in which simple spectroscopic features arise out of a complex many-body system.
Energy evolution of the competition between evaporation and direct transfer in the 16O( 6Li,d) reaction
1995, Physics Letters B
The competition between direct α-transfer and deuteron evaporation has been delineated in ¹⁶O(⁶Li,d) for E_cm from 7 to 14 MeV. Between 7 and 11.5 MeV the reaction proceeds via evaporation. At 12 MeV a direct component appears and after 2 MeV the two mechanisms contribute equally. With the present and all previous relevant results, a complete map of the evolution of the two reaction mechanisms has been constructed.
Energy levels of A = 21-44 nuclei (VII)
1990, Nuclear Physics, Section A
The experimentally determined properties of A = 21–44 nuclides are complied and evaluated with special emphasis on nuclear spectroscopy.
Separate tables for each of the nuclides reviewed present the available information about the following properties (in this order):
- •
  - excitation energies E_x,
- •
  - γ-ray branching ratios b(γ),
- •
  - γ-ray mixing ratios σ,
- •
  - lifetimes γ_m or widths Λ,
- •
  - neutron, proton, or α-particle resonances,
- •
  - partial widths,
- •
  - single-nucleon transfer reactions,
- •
  - beta-decay,
- •
  - arguments for spin and parity (J^π) and isospin (T) assignments.
For each nuclide a master table summarizing the “best” or adopted values for E_x, J^π; T and τ_m or Λ precedes the auxiliary tables listed above.
The review of each A-chain concludes with a discussion of isospin multiplets.
Figures are presented of the level schemes of all nuclei and, for each A-chain, an overview of the relative energies of the ground states and lowest analogue states of all nuclei in the chain.
The competition between p2n, dn AND t emission in heavy-ion induced nuclear reactions
1990, Nuclear Physics, Section A
The competition between p2n, dn and t evaporation leading to production of the same residual nuclei has been measured for 6 heavy-ion-induced nuclear reactions, each at several bombarding energies, for target-projectile combinations resulting in compound nuclei 29<A<37. An association of the relative yields for p2n, dn and t emission with the maximum excitation energy available to the residual nucleus demonstrates a systematic trend, the significance and potential applications of which are investigated. The application of the competition method in the delineation of the mechanisms involved in the ⁷Li + ³⁰Si reaction demonstrates that in addition to the tritons, the competing multiparticle exit channels are as well induced by a non-statistical mechanism.
