摘　　要：The half life of Hafnium isotope 182Hf is very important for astro-physics because the occurrence time of some events in the formation of the solar system and the earth can be measured with 182Hf -182W system. The half life value of 182Hf determined by Austrian scientist Vockenhuber in 2004 was theThe half life of Hafnium isotope 182Hf is very important for astro-physics because the occurrence time of some events in the formation of the solar system and the earth can be measured with 182Hf -182W system, The half life value of 182Hf determined by Austrian scientist Vockenhuber in 2004 was the only decent datum up to date. In view of the above-mentioned facts, it is necessary to remeasure again the half life of 182Hfunder oresent conditions to imorove the accuracy of the datum.
