Description

We have looked for delayed neutron emission from targets of Fe, Sn, and Pb irradiated by 44-GeV carbon ions and from Sn and Pb targets in bombardment by 5.04-GeV 4He ions. The purpose of the work was to search for cases of multiple emission of delayed neutrons by isomers with high excitation energies (for example, density isomers). Triple emission of delayed neutrons with a delay of more than 1 sec was not observed with the following upper limits of the cross section for production of the emitters: 6.8x10-30 cm2 for the reaction Sn+4He, 3.4x10-29 cm2 for Pb+4He, 4.5x10-30 cm2 for Fe+12C, 2.7x10-29 cm2 for Sn+12C, and 1.1x10-28 cm2 for Pb+12C
