The decay of 32 s 90Kr and 154 s 90Rb has been studied using NE102 beta detectors and NaI(Tl) and Ge(Li) gamma-ray detectors, singly and in coincidence. Thirteen excited states of 90Rb involving 35 transitions have been identified with excitation energies of 0.1064, 0.1215, 0.2419, 0.3557, 0.6144, 0.6610, 0.7408, 0.8375, 1.2402, 1.6740(1+), 1.7798(1+), 2.1261(1+), and 3.0937(1+) MeV. The 256 s isomeric state at an excitation of 0.1064 MeV (probably 4–) feeds high spin states of 90Sr at 2.2068, 2.4972, 2.5712, 2.9275, 3.5835, 4.1485, 4.3355, and 5.0397 MeV with a total intensity of 12%. The 154 s ground state of 90Rb feeds many low spin states in 90Sr, including the levels at 0.8315, 1.6555, 1.8921, 2.5271, 3.0385, 3.3833, 3.4497, 3.8985, 4.0325, 4.0360, 4.1360, 4.3660, 4.6466, 4.891, 4.921, 4.974, 5.070, 5.091, 5.163, 5.1876, 5.2540, 5.285, and 5.3336 MeV. Sixty-four transitions in 90Sr have been classified in this manner. The decay energy of 90Kr is 4.41 ± 0.03 MeV.

The decay of Pr137 entirely to a 9.0-hour ground state of Ce137 was independently discovered. By allowed electron capture, Ce137 decays predominantly to a low-lying state of La137, with only a 3% branching to a 440-kev excited state. The 440-kev transition is at least predominantly E2 in character.A 34.4-hour isomeric state produced by the La139(p, 3n)Ce137m reaction decays by a 254.5-kev M4 transition to the 9-hour -ground state. A 0.6% branching was found from the isomeric state directly to a small group of apparently high spin states in La137.Studies of mass-separated isotopes confirmed the existence of 1.5-hour Pr137 and 1.0-hour Pr136. The K-capture to positron branching ratios observed in the decay of Pr139, Pr138, Pr137, and Pr136 show that these isotopes decay by allowed transitions to their cerium daughters. Characteristic gamma rays were observed.

Rotationally single-particle and vibrational excitations of deformable odd nuclei with small nonaxiality are investigated with allowance for the interaction of collective and single-particle states. The ratios of excitation energies, of reduced probabilities of E2 transitions, and of quadrupole moments for deformable odd nuclei with small nonaxiality are calculated up to high-spin states.

Γ Ray

The high-spin structure of 193Hg was investigated by in-beam γ-ray spectro­scopic techniques. The tandem accelerator at Daresbury Laboratory, U. K., was used to populate excited states of 193Hg through the reaction 150Nd(48Ca,5n)193Hg at a beam energy of 213 MeV and the EUROGAM detector array was used to de­ tect the γ-rays emitted by the deexciting nuclei. The normal level scheme has been further extended and a new band has been observed. In addition two new ΔI=1 structures of competing dipole and quadrupole transitions were found which will be discussed in detail.

The Relationship

We have studied the relationship between the π-topology and the photo-excited high-spin states of π-conjugated spin systems, 9-anthracen-(3-phenyl-t-butylnitroxide) radical (1m) and 9-anthracen-(4-phenyl-t-butylnitroxide) radical (1p) systems, by time-resolved ESR and transient absorption spectroscopies.

Conversion Coefficients

High spin states of 96Tc populated by the (α,n) reaction using alpha beams from 13 to 27 MeV have been studied. Gamma-ray energies and intensities, gamma–gamma coincidence probabilities, gamma-ray angular distributions, and electron conversion coefficients were determined at 18 MeV. In addition, some results taken at 14 MeV are reported.The high spin structure observed in this work includes the following levels: 49.3(6+), 318.8(6+), 574.7(7+), 926.9(9+), 946.5(8+), 1062.1(8+), 1138.8(8+), 1447.2(9+), 1702.8(10+), 1861.6(9+), 1922.3(11+), 2147.5(11+), 2213.5(10(+)), 2317.2(12+), 2396.8(11(+)), 2599.0((13)+), 2642.4((14)+), and 3020.1(12(+)).These experiments also clarify and extend the information obtained by previous workers. In particular, evidence is adduced for low-lying states at 0.0(7+), 34.3(4+), 45.3(5+), 120.3(3−), 177.0(5+), 226.2(2−), 227.0(4+), and 254.3(3+).The work identifies many other states of intermediate energy.Attenuation coefficients for states in 96Tc are calculated using a theoretical model.
