Search for the $\rm ^{8}{B}(2^+) \rightarrow {^8}Be(0^+)$ transition

The beta decay of $\rm^{8}{B}$ is an important reaction for both solar neutrino physics and understanding the nuclear physics in the mass-8 system. We are searching for the second-forbidden $\rm ^{8}{B}(2^+) \rightarrow {^8}{Be}(0^+, g.s.)$ transition, which has never before been experimentally detected. The observable signature for this transition is the 92-keV $2\alpha$ decay of the ground state of $\rm{^8}{Be}$. This talk will discuss the development of an $\rm^8 B$ radioactive beam at the UW Tandem and our novel technique for measuring the low-energy signature of this transition. A branching-ratio limit will be given, as well as a comparison of this limit to theoretical estimates.
