Induced Radioactivity in Cadmium and Indium

Discovery of the calcium, indium, tin, and platinum isotopes

“…The measured half-life is in reasonable agreement with the currently accepted value of 13.9(6) s. A previous attempt to identify 50 Ca did not succeed [25]. 51 …”

“…Decay curves of γ -ray spectra were measured. ''From the decay of the six strongest lines in the multispectrum, the half-life of 51 52 Ca, and 52 Sc; a test of the shell model far from stability'' [28]. A uranium target was fragmented by 600 MeV protons at the CERN synchrotron.…”

“…51 K was produced by bombarding uranium with 600 MeV protons at the CERN synchrotron, which decayed to 51 Ca through positron emission. Decay curves of γ -ray spectra were measured.…”

Symmetry Energy and the Isotopic Spin Dependence of the Single-Particle Potential in Nuclear Matter

“…INTRODUCTIONT HE decay of Cd 117 was first investigated by Cork and Lawson 1. They used {d,p) reaction on Cd and identified the Cd 117 activity of 3.75-h half-life from its daughter In 117 .…”

Discovery of the cadmium isotopes

“…A few months later Mitchell [29] measured half-lives of 52 h and 5 h, agreeing with the assignment by Cork and Thornton. Seven months after the submission of the Goldhaber paper, Cork and Lawson independently reversed their assignment of newly measured half-lives of 56 h and 3.75 h to 115 Cd and 117 Cd, respectively [30]. It should be noted that Aston had incorrectly reported the observation of stable 115 Cd in 1935 [15].…”
