IDS collaboration meeting:
- Frame is not sure yet whether or not we can have it, maybe we make a duplicate of the IDS frame
- IDS coming is 95% sure according to Thomas, besides the 6 Leuven clovers are guaranteed to come
- Idea to make a plot that shows the dynamic effect where we make a plot with R, N and Z

Quartet meeting (ECT* meeting): Quartet meeting
ISNT meeting oktober from Karim, 14-17 October in Paris
Michael
Extraction of k and alpha:
- weighting with r2 rho(r) (as the region where the approx has to hold is there where r2rho(r) is big) and not r4 rho(r) because argument can not be reproduced
- different k and alha values for different np1s lines are very similar --> Use average isntead
Electron screening: small effect and we will include it as a correction
V2 from BSkG:
- use BSkG4 --> Nice agreement with experimental results
- relative uncertainty of 0.05% --> factor 2.5 better than experimental values for Cl
Nuclear polarization: (see also: https://arxiv.org/abs/2501.15274 and https://www.sciencedirect.com/science/article/pii/S0092640X74800033)
- Nuclear part = Pygmy and Giant resonance
- nucleon part = individual particle contribution
- Linear addition of the three uncertainty contributions to have a total nuclear polarization correction
- Uncertainties on the differences:
- initial idea does not work as the relative error on Pygmy >> relative error on (Pygmy + Giant resonance)
- Instead: calculate correlated fraction f1 and f2 (Corr(NP1,NP2) = f1 x f2)
- With this method the difference of nuclear polarizations for 37 and 35Cl = -3(12)eV
- There should be a more involved table of the different contributions of QED that Paul takes into account: Michael, Ben and Randolf will have a meeting for this
- In general an overview theory paper would be nice
There are minutes attached to this event.
