THE 199Hg(n, γ)200Hg REACTION WITH THERMAL NEUTRONS

Abstract
Thermal neutron-capture γ rays from 199Hg(n, γ)200Hg were studied with a lithium germanium detector and with angular correlation techniques. Gamma-ray and level energies were determined with accuracies of at best ±3 keV. Spin 0 for the capturing state was confirmed and levels at 1 569, 2 060, 2 369, 2 640, 3 186, 3 269, 3 289, 3 351 keV were assigned spin 1. The 200Hg level scheme is discussed.
