Discover Ne^9 Energy Levels Using NIST Database - Missing Values?

Click For Summary
SUMMARY

The discussion centers on the missing energy levels for Ne^9 as retrieved from the NIST database. Specific energy levels are provided, with several values marked as missing. Users are seeking assistance in locating these missing values or alternative sources for the data. The conversation highlights the importance of NIST data in determining energy transitions and suggests that additional information on transitions from other states may help in calculating the missing energy levels.

PREREQUISITES
  • Familiarity with atomic structure and energy levels
  • Understanding of the NIST Atomic Spectra Database
  • Basic knowledge of quantum mechanics and electron transitions
  • Experience with data analysis in scientific research
NEXT STEPS
  • Research the NIST Atomic Spectra Database for Ne^9 energy levels
  • Explore methods for calculating missing energy levels using known transitions
  • Study quantum mechanics principles related to electron transitions and energy states
  • Investigate alternative databases or publications for atomic energy levels
USEFUL FOR

Researchers, physicists, and students in atomic physics or quantum mechanics who are working with atomic energy levels and require accurate data for Ne^9.

Using the NIST database, I get the following energy levels for Ne^9.

But there some some values missing (where the ? is shown).

Any of you know these numbers, or where I can find them?

Thanks.

The transitions might be too exotic. If NIST has data for transitions from these states to other states, and then from the other states to 1s, then you can add the energy differences.
