Abstract
The half-life of the first excited states of150Nd,152Sm,154Sm,160Gd and170Er have been measured by pulsed beam-technique. Using the slope-method and a momentumanalysis we get the following results:150Nd 131 keV-levelT 1/2=(1.48±0.04) ns152Sm 122 keV-levelT 1/2=(1.44±0.03) ns154Sm 82 keV-levelT 1/2=(3.00±0.06) ns160Gd 75 keV-levelT 1/2=(2.68±0.06) ns170Er 79 keV-levelT 1/2=(1.88±0.05) ns
