Double-electron capture of 74Se and the search for neutrinoless decay
TL;DR: In this paper, the double-electron capture (EE) decay process of 74Se was investigated and the 2γ-ray cascade was detected by a HPGe γ-ray detector in coincidence with a NaI detector using 3 kg of natural selenium.

TL;DR: In this article, a model-independent mechanism was proposed to identify states near the proton threshold energy in 19Ne corresponding to Δ L=0$ transitions, which could significantly affect the 18F(p,$\alpha$) astrophysical S-factor at nova burning temperatures.

Abstract: . Nuclear matrix elements (NMEs) for double beta decays (DBDs) are crucial for studying the neutrino mass and other neutrino properties beyond the standard electro-weak model by measuring neutrino-less DBDs. The spin-dipole (SD) J π =2 − NME is one of the major components associated with the DBD NME. The SD NME for 76 Ge was derived for the first time by using the ( 3 He, t ) charge-exchange reactions (CERs) on 74 , 76 Ge at RCNP Osaka. The obtained SD NME for the 76 Ge → 76 As ground-state transition is | M − EXP ( SD ) | =1.5 × 10 − 3 in natural units. This is smaller by a coefficient around k ≈ 0.2 with respect to the quasi-particle (QP) model NME | M − QP ( SD ) | . The impact of the reduced (quenched) SD NME on DBD neutrino studies is discussed.
A technique for the preparation of thin self-supporting metallic gallium targets
TL;DR: In this paper, self-supporting gallium targets (nat Ga, 69 Ga, 71 Ga) with areal densities varying between 2 and 4mg/cm 2 have been produced for a medium-energy (3 He, t ) nuclear scattering experiment.
