摘要: In-beam time-sorted measurements of internal-conversion electrons, ..gamma.. rays, and ..gamma..-..gamma.. coincidence are reported for /sup 206/Pb. The range measurable kinetic energies electrons was approx.40--1600 KeV with powder targets using the reaction 204/Hg(..cap alpha..,2n)/sup results confirm yrast 12+, 10+, 9- levels in 206/Pb which, based on partial evidence, were tentatively proposed by group Stockholm. effective quadrupole charge i/sub 13/2/ neutron is (0.89 +- 0.05) e. Conversion coefficients multipolarities 10 transitions reported.
