Since the discovery of neutrino oscillations, we know that neutrinos have non-zero mass. However, the absolute neutrino-mass scale remains unknown. Here we report the upper limits on effective electron anti-neutrino mass, mν, from the second physics

Experimental evidence of (M1+E2) mixed character of the 9.2 keV transition in $^{227}$Th and its consequence for spin-interpretation of low-lying levels

Autor: Koval��k, A., Inoyatov, A. Kh., Perevoshchikov, L. L., Ry��av��, M., Filosofov, . D. V., Alexa, P., Kvasil, J.

The 9.2 keV nuclear transition in $^{227}$Th populated in the $\beta$-decay of $^{227}$Ac was studied by means of the internal conversion electron spectroscopy. Its multipolarity was proved to be of mixed character M1+E2 and the spectroscopic admixtu
