The decay of the isotope ba133, produced by pile neutron irradiation of ba132, has been studied with a magnetic lens and scintillation spectrometers.
Le baryum 133 se d esint egre par capture electronique vers des niveaux excit es de 437 et 383 kev du c esium 133. Gamma rays at 79, 79, 274, 302, 358 and 381 kev have been observed. The nuclide box extract, the decay scheme is shown giving more details of the decay processes. Most of the recent investigators 7, s, 14) are in agreement concerning the salient features of the electron capture decay scheme of 7.2 y ba i 3 a as shown in fig.

Fast neutron activation thermal neutron activation : 133ba disintegrates by electron capture mainly to two133cs excited levels of 437 kev (85.4%) and of 383 kev (14.5%) with three very minor branches to the 160 kev, 81 kev excited levels and the ground state. Gamma rays at 79, 79, 274, 302, 358 and 381 kev have been observed. These decay schemes are an aid to understanding the contents of the nuclide chart boxes.
