128. CRAB: Calibration by Recoils for Accurate Bolometry at the 100 eV scale using neutron capture – on the shore of particle, nuclear and solid state physics

Fundamental Symmetries and Interactions

Invited Oral

The detection of the coherent elastic neutrino-nucleus scattering (CEνNS) at reactors or of an hypothetical light dark matter (DM) particles will allow to test new physics beyond the standard model. In both cases their direct detection will lead to sub-keV nuclear recoils. This requires low energy thresholds of few 10 eV along with energy resolutions of few eV, which can be achieved by...

120. Advancements of $\gamma$-ray spectroscopy of isotopically identified fission fragments with AGATA and VAMOS++

Experimental Nuclear Structure

Invited Oral

The utilization of nuclear fission as a method to investigate the nuclear structure properties has been widely employed for several decades. This approach offers an effective means of producing neutron-rich exotic nuclei, covering a broad region of the nuclear chart. By studying the properties of fission fragments, a diverse range of phenomena, including shell closure effects, collective...

Nuclear Data

Invited Oral

Fission yields are one of the most used observables to describe the fission process. They are also mandatory for nuclear fuel cycle studies or nuclear reactor calculations. A collaboration between CEA, LPSC, and ILL has been working since 2010 on the LOHENGRIN spectrometer in order to better control the possible experimental biases and systematic uncertainties.
Different setups allow us to...

133. A new technique to determine gamma emission probability above the neutron threshold without gamma-ray detectors

Nobu Imai (Center for Nuclear Study, University of Tokyo)

Experimental Techniques

Invited Oral

Evaluation of the neutron-capture reaction rates on radioactive isotopes is still challenging. Several indirect methods have been proposed to evaluate the cross sections. We recently developed a novel technique to determine the gamma emission probabilities of the unbound states in a nucleus without detecting gamma-rays. By employing the idea of the surrogate reaction, the neutron capture...
