10. Gamma-ray and conversion electron spectroscopy on irradiated targets

We propose to irradiate different targets in the ISOL bunker 2 to then perform off-line $\gamma$-ray and conversion $e^-$ spectroscopy on the long-living isotopes (at least 30 min) created by the 35-70 MeV protons. After irradiation, the targets can be placed in measurement setups like the b-DS tape station outside the bunker where detailed spectroscopy can be performed.
We highlight two...

7. High-precision tests of the Pauli Exclusion Principle in proton-nucleus interactions using the SPES Cyclotron

Introduction & Scientific Motivation: The Pauli Exclusion Principle (PEP) is one of the fundamental tenets of quantum mechanics, dictating the behavior of identical fermions within a system. While extensively tested (by us) for electrons within the VIP (VIolation of the Pauli exclusion principle) experiment using high-precision X-ray spectroscopy [1], its validity for nucleons remains an open...

15. Neutrino physics from gamma-ray spectroscopy

Nuclear matrix elements (NMEs) are crucial for understanding weak interaction processes such as inverse beta decay (IBD) and neutrinoless double-beta decay (0νββ), which provide insights into neutrino properties and physics beyond the Standard Model. A novel experimental approach aims to extract NMEs using electromagnetic (EM) transitions from isobaric analog states (IAS). In this Expression...

6. Production at SPES of a 94Nb radioactive source for studying the quenching of the weak interaction axial-vector coupling constant

The present proposal aims at the production of a solid state 94Nb beta-emitting radioactive source via the proton irradiation of a 94ZrO2 thin film (~200 μg/〖cm〗^2 areal density) evaporated onto a multilayer graphene (MLG) sheet, via 94Zr(p,n)94Nb reaction at 35 MeV incident energy. The source will be exposed to an array of silicon drift detectors (SDD) in order to study the shapes of the beta...
