This is an outcome of a workshop devoted to E0 transitions in atomic nuclei, held at Australian National University, Canberra, Australia, Sept 11-12 , 2015, organized by Tibor Kibèdi (Chair), Andrew Stuchbery, and Greg Lane.

E0 Focus Group - mission statement

edit

To my knowledge, in the 40 years that I have been engaged in studies of nuclear structure, with an active interest in E0 transitions in atomic nuclei, this was the first-ever meeting dedicated to the topic.

It was decided by the attendees that this was a unique opportunity to launch a focus group with interest in E0 transitions in atomic nuclei and topics related to this subject. Therefore, this Wiki is a commencement of this resolve.

A leading interest in E0 transitions is their association with shape coexistence in atomic nuclei. Also, this is the only process by which a transition can occur between two nuclear states, each having spin parity 0+.

I anticipate that the wiki initiated herewith will evolve into a documentation of the E0 process--its history, manifestations, underlying physics, and role in the elucidation of nuclear structure. The last aspect of the E0 process will be the dominant theme. — John L. Wood

Key criteria for E0 studies

edit

Experimental

  • Measurement of Ice or Iπ is difficult
  • Determination of δ(E2/M1), for E2+M1+E0 transitions, is difficult. (Multi-detector geometries, angular momentum algebra)
  • Measurement of T1/2 is difficult. (Needs decision on electronic timing versus RDDS or DSAM, indirect feeding issues.)
  • Demonstrating "no γ-rays" for pure E0 is difficult.

Theoretical

  • Straightforward for two-state mixing and Δ<r2> prescription.
  • Need to explore Paul Garret`s approach to two-state mixing and Δ<β2> prescription via E2 matrix elements and Kumar-Cline sum rules.

General remarks

  • There is a lack of familiarity with the formulation of E0 transition strength, both with the experimental input quantities and with the theoretical details.
  • Experimental demands are likely regarded as intimidating by most persons.
  • Two-state mixing involves "a lot" of parameters.
  • ENSDF does not handle E0 transition strength in any well-defined manner
  • Treatment of E0 transition strength in various theoretical frameworks is haphazard because the model-dependent formulation of the E0 operator is ambiguous. Also, theorists are not familiar with the available data because it is not in ENSDF.
  • There does not appear to be an obvious "unit" suited to quantify E0 transition strength. (Note that ρ2(E0) is dimensionless.)
