The 7.02-MeV level of 20Ne has been studied by the I2C(12C, αγ)20Ne reaction, using angular correlation techniques, with a particle counter and six Nal crystals. The spin and parity of this level were determined to be 4−. The branching ratio of the decays to the 5.63, 4.97, and 4.25 MeV levels was found to be 22:65:13. The transition to the 5.63-MeV state (4− → 3−) is an almost pure E2 transition with an M1/E2 amplitude ratio of 0.03 ± 0.03. The branching ratio of the E2 transitions to the 5.63-MeV 3− level and the 4.97-MeV 2− level is in excellent agreement with predictions from the rotational model and also with SU3 calculations.Similar measurements on the 10.65-MeV level in 20Ne support the tentative 6− assignment to this level.

Level energies and details of the γ-ray decay scheme in 51Cr are determined by Ge(Li) spectrometer and angular correlation techniques. Spin 3/2 is assigned to levels at 0.748, 1.898, 2.893, 3.125, and 3.769 MeV. A level at 776 keV, for which spin 1/2– is favored, may account for the anomalous lifetime previously reported for the 748-keV γ ray in 51Cr.

Thermal neutron-capture γ rays from 199Hg(n, γ)200Hg were studied with a lithium germanium detector and with angular correlation techniques. Gamma-ray and level energies were determined with accuracies of at best ±3 keV. Spin 0 for the capturing state was confirmed and levels at 1 569, 2 060, 2 369, 2 640, 3 186, 3 269, 3 289, 3 351 keV were assigned spin 1. The 200Hg level scheme is discussed.

A new method for determining the amount of magnetic quenching of the orthopositronium atom is described. This method, still using angular correlation techniques, allows a direct measure of the quantities which the orthopositronium magnetic quenching deals with. By this way, an experimental measurement has been performed, as a check, in water at temperature T = 20 °C and with a magnetic field H = 10 kG. The obtained value ΔIs = (1.73 ± 0.22)% is in very good agreement with the theoretical one.
