Experimental study of the electromagnetic decays of the #betta# and μ excited states

Electromagnetic decays have served as bench marks in the developing stages of the shell model in nuclei. The quark confinement pictures for baryons are now in a similar developing stage. This experiment will test in an unambiguous way, the configurations present in the low lying excited states of the #betta# and μ by measuring the electromagnetic branching ratios that connect them. Experimentally, about half of the decays should be measured at FNAL using the hyperon beam via the Primakoff effect. The remaining transitions, including the very interesting forbidden ones, will require the K fluxes and purities available at LAMPF II
