Abstract

NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document.

The [...]-rays emitted from traces of Co58 aligned in single crystals of (xNi, (1-x)Zn, Co58)SiF6.6H2O have been studied with various nickel fractions (x) between 0 and 0.19.

These experiments were designed to determine the fraction of Fermi decays ([...]) in the Co58 [beta]-decay. Results using a 0% nickel crystal indicate a small dealignment of the 10(-11) second intermediate state which just precedes the emission of the 810 kev [...]-ray. In addition, the nuclear alignment is found to be strongly influenced by the presence of paramagnetic nickel ions in the nickel bearing crystals. Because of the dealignment in the intermediate state, it is not possible to assign a definite value for [...]. However, indications are that [...] is near to zero.
