Precision measurement of the ²¹⁰Bi β spectrum

RADIOACTIVITY ²¹⁰Bi(β^-)[from ²¹⁰Pb β^- decay]; measured Eβ, Iβ, x rays, ce using Si(Li) detector; deduced β shape factors for the first forbidden nonunique β transition. Comparison of measured β spectrum with previous experimental results. ²⁰⁷Bi(EC), (β⁺); measured x rays, ce to determine thickness of the nonsensitive layer on the surface of Si(Li) detector. ²¹⁰Pb(β^-); observed β^- spectrum. ²¹⁰Po(α); observed α spectrum.
