v1.2

Changes

• bugfix of exp_s (and std_s)
• bugfix of exp_j for states with hyperfine structure (e.g. Yb171)
• is_calculated_with_mqdt now is False for models with only one channel
• use nu bounds from models
• add more low n models and include these low n states in the database
• Yb173_mqdt fixed a few cases, where the exact same state was included twice (e.g. nu=42.5, exp_l=1)
• Sr88_mqdt fixed nu of F states
• also add high l states for isotopes with hyperfine structure (up to n=110, see details below)

Details

• Include all states with principal quantum number up to nu = 220, with the following exceptions:
  • High l SQDT states are only included for nu > 25 (check if this is needed for the next release)
  • Low l MQDT models are included for low and high nu states (Sr so far only has one low nu model, while Yb171 and Yb174 have multiple models, which where fitted to NIST data, see also here). However, there might be some states missing at the transition between low nu and high nu models, this will be addressed in a future version, see this issue to see the current status)
  • For Yb171, Yb173 and Sr87 and nu > 110, only states up to l = 10 are included (otherwise the database size is too large)
• Include matrix elements for |n_initial - n_final| <= max_delta_n = 10

v1.1

Changes

• First automatic build of database tables via github ci
• add higher n states for all species
• add high l states for Yb174 and Sr88
• use ryd-numerov for SQDT radial wavefunctions and matrix elements

Details

• Include states with principal quantum number from n = 25 up to n = 220 (for Yb173 only up to n = 130)
• Include matrix elements for |n_initial - n_final| <= max_delta_n = 10
• For Yb174 and Sr88 include also all high l states described by SQDT
