AbstractAbstract
[en] For the decay of 49Cr the intensities of the 1361-, 1423-, 1508-, 1514-, and 1570-keV γ rays are found to be 0.85, 0.19, 0.15, 0.49, and 0.37, respectively, relative to I/sub gamma/ = 1000 for the 90-keV γ ray. Four other previously reported γ rays are shown to be sum peaks or contaminants. The recalculated β-decay branches and logft values (in parentheses) for 49Cr decay are ground state (5.51), 90.639- (4.94), 152.928- (4.74), 1514.5- (5.71), 1661.1- (6.06), 2181.7- (7.0), 2236- (6.6), and 2310-keV (7.1). The known 3/2+ level at 748 keV was not observed to be populated and a limit of logft > 9 was found for that level

AbstractAbstract
[en] The external heavy atom induced phosphorescence of C60 and C70 is obtained at 77 K in a glass containing ethyl iodide and gives 12 690 ± 30 cm-1 as a precise lower limit for the energy of triplet C60. Triplet lifetime measurements show that the heavy atom effect is relatively much greater on the S1 → T1 than on the T1 → S0 radiationless transitions, as expected from the smaller Franck-Condon constraints in the former process. 26 refs., 2 figs

AbstractAbstract
[en] A new program studying the behavior of nuclear matter under very high excitation was begun at the Bevatron with experiments designed to study the gamma radiation emitted from central collisions of heavy ions. A system was partially completed that made use of a multiplicity detector as a signature of a central collision. The system was surrounded by gamma detectors for both the nuclear and high-energy range; such an arrangement yielded a very large acceptance. A preliminary experiment showed the feasibility of the system and gave the first results of correlations of gamma rays with such collisions. Some details of both the system and the preliminary results are described. Experiments on the measurement of nuclear moments from beta emission are reviewed, and the final results for the latest measurements on 9Li are given. Results of recent measurements on gamma polarization from high-spin states of 105-109Cd are also presented. Studies of electrons resulting from heavy ion collisions using a special high-acceptance beta spectrometer are described. The preliminary results indicate the beginnings of effects that are complements of the so-called combined atom x-ray phenomena. A new program for the study of gamma rays and neutrons produced in the capture of pi meson of nuclei are described with some new results on the excitation of high-spin states. Finally, a reprint of a recent evaluation of some old data concerned with the conserved vector current theory is added

AbstractAbstract
[en] In this paper, we explored the characteristics of the interference effects between perturbative states in hyperfine induced 2s2p 3P0, 3P2 → 2s21S0 transitions of Be-like ions. It was found that the interference effects non-monotonically change with increasing atomic number Z in these two transitions. The strongest interference effect is near Z = 9 for 2s2p 3P0 → 2s21S0 transition and near Z = 7 for the other.
