The 2.5 minute Ba daughter of Cs¹³⁷ by D. W Engelkemeir( )

3 editions published in 1948 in English and held by 25 WorldCat member libraries worldwide

An isomeric state of stable Ba(137) which decays by gamma emission to the ground state with a half-life of 2.5 minutes has been discovered. This metastable state is formed by beta-decay of Cs(137). The Ba(137) gamma has an energy of 0.75 Mev and is 13% internally converted giving rise to approx 0.7 Mev conversion electrons and K x-rays
Radiations of 6.7d U237 by F Wagner( )

2 editions published in 1952 in English and held by 21 WorldCat member libraries worldwide

The radiations of U237 have been studied using a magnetic lens beta ray spectrometer and scintillation spectrometers for betas and gammas singly and in coincidence. A beta with an end point energy of 245 (plus or minus) 5 kev was found along with evidence for the existence of a lower energy component. Gammas of energy 27, 43, 59, 165, 207, 269, 334, 370, and 430 kev were found, and probably a gamma of 102 kev. The decay scheme constructed gives a total decay energy for this isotope of 511 (plus or minus) 5 kev
Radiation from 120-day Ta182 by D. W Engelkemeir( Book )

2 editions published in 1950 in English and held by 9 WorldCat member libraries worldwide

A survey of the literature combined with some new work done at this laboratory provides a list of the chief radiations from Ta182
