Experimental search for interference effects in the total e(-)+Sc3+ recombination rate

In a recent theoretical paper Gorczyca el nl. [Phys. Rev. A 56, 4742 (1997) ] predicted interference between radiative and dielectronic recombination t o show up in the total recombination rate coefficient of Ar-like Sc3+(3s(2) 3p(6)) with the signature of interference bring an asymmetric line profile of the 3s(2)3p(5)3d(2) F-2 dielectronic recombination resonance. Due to lim ited counting statistics our experimental result obtained at the Test Stora ge Ring at the Heidelberg Max-Planck-Institut for Nuclear Physics does not permit a detailed line-shape analysis to be carried out. However, differenc es between theory and experiment remain to be explained. [S1050-2947(99)069 03-8].
