Abstract

The 137I/87Br and 88Br/87Br delayed neutron ratios were measured respectively as 4.85 + 0.20 and 1.7 + 0.2 after chemical separation from thermal neutron fission of 235U. Delayed neutron yields are proposed for 87Br, 88Br and 137I and the halflives of 87Br and 137I are remeasured with higher precision. By comparing the neutron activities of 87Br and 137I to the γ-ac-tivities of their daughters 87Kr and 137Xe, their Pn values are evaluated.
