The evidence obtained for the existence of the K X-ray gamma-ray directional correlation by Perepelkin against the predictions of the theory of Dolginov evoked considerable interest in this field. The electron capture decay of 114Inm is used to advantage in the present investigation with a sum-peak-coincidence scintillation spectrometer. The results obtained are consistent with the theory of Dolginov.

In the electron-capture decay of 144Pm prepared by (p, 2n) reaction on enriched 145Nd, it is shown that, in addition to the well-known energy levels at 696, 1313, and 1789 keV, two new levels exist, one at 2093 keV, and another at 1509 keV. The state at 2093 keV deexcites with the emission of a 304-keV gamma ray to the 6+ level at 1789 keV, and by a crossover transition to the 4+ level at 1313 keV with the emission of a 780-keV gamma ray. The level at 1509 keV leads to the first excited state (2+) at 696 keV with the emission of a gamma ray of energy 813 keV. The intensities of the 780-, 304-, and 813-keV gamma rays are, respectively, 1.5, ≈ 0.1, and 0.5% of that of the 696-keV gamma ray.

We have detected six narrow-line Seyfert 1 (NLS1) galaxies at 37 GHz that were previously classified as radio silent and two that were classified as radio quiet. These detections reveal the presumption that NLS1 galaxies labelled radio quiet or radio silent and hosted by spiral galaxies are unable to launch jets to be incorrect. The detections are a plausible indicator of the presence of a powerful, most likely relativistic jet because this intensity of emission at 37 GHz cannot be explained by, for example, radiation from supernova remnants. Additionally, one of the detected NLS1 galaxies is a newly discovered source of gamma rays and three others are candidates for future detections.
