Abstract

A homogeneous magnetic field beta spectrometer and its completely automatic control system are described. Momentum resolution is such that a monoenergetic line has a full width at half maximum intensity of 0.22%. The instrument was used to analyze the conversion line spectrum of the 411‐kev gamma ray from Hg¹⁹⁸. The data give for the conversion ratios K:L:M:N values of 1:0.361:0.100:0.027; and for (L_I+L_II): L_III, the value 5.9.
