Abstract

The strengths of the isospin forbidden E1 ground-state transitions from the 1⁻, 6.95 MeV state of ⁴⁰Ca and the 1⁻, 7.12 MeV state of ¹⁶O were determined in a γ-ray resonance scattering experiment; the partial widths are Γ_O = 0.41 ± 0.08 eV and 0.06 ± 0.01 eV, respectively. The results are in good agreement with previous determinations, confirming the unusually large strengths of these E1 transitions. In addition, the widths of the 2⁺, 6.91 MeV state of ⁴⁰Ca and the 2⁺, 6.92 MeV state of ¹⁶O were measured as Γ_O = 0.13 ± 0.06 eV and 0.094 ± 0.010 eV, respectively.

Observation of isoscalar and isovector dipole excitations in neutron-rich <sup>20</sup>O
2017, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
The isospin characters of low-energy dipole excitations in neutron-rich unstable nucleus ²⁰O were investigated, for the first time in unstable nuclei. Two spectra obtained from a dominant isovector probe ( ${}^{20}O + Au$ ) and a dominant isoscalar probe ( ${}^{20}O + α$ ) were compared and analyzed by the distorted-wave Born approximation to extract independently the isovector and isoscalar dipole strengths. Two known $1^{-}$ states with large isovector dipole strengths at energies of 5.36(5) MeV ( $1_{1}^{-}$ ) and 6.84(7) MeV ( $1_{2}^{-}$ ) were also excited by the isoscalar probe. These two states were found to have different isoscalar dipole strengths, 2.70(32)% ( $1_{1}^{-}$ ) and 0.67(12)% ( $1_{2}^{-}$ ), respectively, in exhaustion of the isoscalar dipole-energy-weighted sum rule. The difference in isoscalar strength indicated that they have different underlying structures.
Nuclear Data Sheets for A=40
2017, Nuclear Data Sheets
The experimental nuclear structure data and decay data are evaluated for the known nuclides of mass 40 (Mg, Al, Si, P, S, Cl, Ar, K, Ca, Sc, Ti). Detailed evaluated nuclear structure information is presented with the best values recommended for level energies, half-lives, γ-ray energies and intensities, decay properties (energies, intensities and placement of radiations), and other spectroscopic data. The ⁴⁰Ca and ⁴⁰K nuclides remain as the most extensively studied from many different reactions and decays; no excited states are known in ⁴⁰Mg, ⁴⁰Al, ⁴⁰P and ⁴⁰Ti. This work supersedes the earlier full evaluation of A=40 by J. Cameron and B. Singh (2004Ca38).
Nuclear data sheets for A = 40
2004, Nuclear Data Sheets
Nuclear spectroscopic information for the known nuclides of mass 40 (Al,Si,P,S,Cl,Ar,K,Ca,Sc,Ti) has been evaluated. The principal sources of the adopted levels presented are Endt's evaluations (1990En08, 1978En02). The data sets for reactions and decays, including all available gamma-ray data, are based mostly on the original literature. There are no data available for the excited states in ⁴⁰Al, ⁴⁰Si, ⁴⁰P and ⁴⁰Ti. The identification and particle stability of ⁴⁰Mg are still uncertain, although search for this nuclide has been made (2002Lu09,2002No11,2003Pe31).
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.
Strengths of gamma-ray transitions in A = 6-44 nuclei (III)
1979, Atomic Data and Nuclear Data Tables
The present tables list the strengths (in Weisskopf units) of over 2400 γ-ray transitions in A = 6–44 nuclei, classified according to character (electric or magnetic, multipolarity, isospin forbiddenness). Selected transitions from unbound states are included. The strengths for isovector E1 and M1 transitions (E1_IV and M1_IV) show a marked decrease with A. Strengths depended very little on the excitation energy of the initial state. The new data incorporated in the table haave not given rise to changes in the recommended upper limits (RUL) for γ-ray strengths presently in use. The only exception is the (spectroscopically unimportant) RUL for E1_IV transitions which should be raised from 0.1 to 0.3 W.u. for A = 6–20 nuclei.
