Abstract: | <p>The modes of disintegration of four erbium isotopes will be discussed.</p> <p>The simple decays of Er<sup>163</sup>, Er<sup>165</sup>, and Er<sup>169</sup> have been investigated experimentally using scintillation spectrometer techniques. The disintegration of the fourth isotope, Er<sup>171</sup>, was analyzed using the high resolution beta-ray spectrometer. On the basis of the energy, intensity, and conversion coefficient measurements of the transitions in Tm<sup>171</sup>, an energy level scheme for this nucleus is proposed and interpreted according to the unified nuclear model.</p> <p>In addition, a set of experiments will be discussed which were carried out in order to calibrate the high resolution beta-ray spectrometer for gamma-ray intensity measurements. Finally, the already published results of an investigation of the decay of Pm<sup>149</sup> will be included.</p> |
