    Directional correlation measurements were performed on seven cascades involving the gamma rays in W The angular momenta of the excited states and the character of the gamma transitions which were determined by the correlation measurements are in good agreement with the values as determined by previous investigators. There is evidence for the existence of three rotational bands with the. GAMMA-GAMMA DIRECTIONAL CORRELATION MEASUREMENTS IN THE DECAY OF Ba lss L. I. YIN and M. L. WIEDENBECK Harrison M.

    The beta-gamma angular correlation for Sb¹²⁴ has been measured as a function of the beta particle energy in the range from Mev to the end of the beta particle spectrum ( Mev). As a beta particle spectrometer, use was made of a twelve channel kicksorter and a thick crystal beta particle scintillation counter. This was connected in coincidence with a gamma ray scintillation counter. The decay schemes of {sub 28}{sup 58}Ni, {sub 29}{sup 61}Cu, and {sub 30}{sup 61}Zn have been extended with the results of gamma-gamma coincidences and directional correlation from .

Gamma-gamma directional correlation study of barium Public Deposited. Gamma-gamma directional correlations were measured in Ba¹³⁴ at ten angles between 90 degrees and degrees in ten degree increments using a scintillation spectrometer.

The spectrometer which used NaI crystals, differential energy selection, and standard Author: Lamar William Coleman. In Brady and Deutsch 1 introduced gamma-gamma directional correlation measurements.

Since then this kind of experimental investigation has become a standard technique in nuclear spectroscopy. Far less attention has been paid to the closely related electron-gamma directional correlation measurements though some pioneering work was done already in by Frauenfelder and co Author: T.R.

The values of the correlation coefficients for the (–), () and () keV cascades after correcting for background coincidences and solid angle areA 2=−±,A 4=+±;A. The directional correlations of the –keV and the –keV gamma-ray cascades observed in the decay of Ru have been studied.

Dilute liquid sources (RuCl2 in HCl) of varying activity. Since this work is concerned with the directional correlation of a gamma-gamma cascade, we will restrict ourselves to a discussion of the theory involved in this type of emission. In the following, references to "angular correlation", without qualifying phrases or adjectives, will be concerned with the direction-direction gamma-gamma cascade in.

The level structure ofPm is studied with a high-efficiency sum coincidence spectrometer. The levels atand keV are confirmed and their decay modes are also proposed. The gamma-gamma directional correlations involving the (–) and (–91) keV cascades inPm are studied.

It is true that perturbed angular correlations had been discussed at a smalI, highly - specialised meeting at Uppsala in and that in The angular correlation of successive gamma-rays emitted by six even-even nuclei has been investigated and found to be anisotropic in every case, and of the magnitude expected theoretically.

An experiment was performed on {sup }Ce to measure E2/M1 multipole mixing ratios using the method of {gamma}{gamma} angular correlations. The low-spin states of interest were populated by {beta} decay from the 2{sup +} ground state of {sup }Pr that has a half-life of min.
