Deliverables

• Deliverable D1

• Deliverable D2

Report describing the influence of different decay schemes of radionuclides (such as pure electron-capture of ⁵⁵Fe, β/γ-decay of ¹²⁹I or α/γ-decay of ²⁴¹Am) on activity standardisation and the requirements for statistical uncertainties < 0.1 % using low temperature detector-based spectrometers

• Deliverable D3

• Deliverable D4

Summary report of five open access papers, based on experimental results, submitted to peer review journals describing:

a) the MMC spectrometer extension for multiple channel
measurements >10⁸ events per spectrum
b) the validation of MMC activity standardisation of ²⁴¹Am
c) the MMC source preparation with ion-implantation
d) the high-resolution, high statistics measurement of the ⁵⁵Fe EC
spectrum a lower energy threshold (< 50 eV)
e) the high-resolution, high statistics measurement of the ¹²⁹I beta
spectrum to determine the beta spectrum shape of ¹²⁹I down to 0 keV

• Deliverable D5

Report summarising the comparison of experimental spectra of ⁵⁵Fe and ¹²⁹I with high-precision theoretical predictions.

• Deliverable D6

Summary report of three open access papers, based on
theoretical reviews, submitted to peer review journals
describing:
a) the high-precision calculation of electron captures with the
improved DFT code
b) the high-precision atomic parameters calculations of ⁵⁵Fe
electron-capture decay
c) the improved calculation of energy spectra of the beta
particles emitted in ¹²⁹I decay
