INVESTIGATION OF H4 AND LI4 FOR ASTROPHYSICAL APPLICATIONS
Abstract
A search for H-4 and Li-4 was made by looking for radioactivities produced in the following reactions: He-3 (p,gamma) Li-4, He-3 (d,n) Li-4, H-3 (d,p) H-4, H-3 (n,gamma) H-4, and Li-7 (n,alpha) H-4. The possible existence of Li-4 was also studied by direct observation of the gamma rays produced in the He-3 (p,gamma) Li-4 reaction. i n none of the measurements was any evidence seen for the existence of Li-4 or H-4. From the activation runs, upper limits to the cross sections were obtained as a function of lifetime, for half-lives extending from as short as 10 to the -6th power seconds to as long as 10 to the 5th power seconds. The various reactions were investigated over different portions of the half-life range. The results obtained provide evidence that neither Li-4 nor H-4 is particle-stable.
