Favoured alpha decays of odd-mass nuclei

摘要: The authors examine the alpha decays of heavy odd-mass nuclei, selecting those transitions which appear to proceed with least hindrance due nuclear structure incompatibilities between parent and daughter. They analyse half-lives 255 these favoured using a simple cluster model, reproduce absolute values 216 them within factor 3. achieve this level agreement exactly same set model parameter previously employed in an analysis decay even-even nuclei. In that 125 out total 154 were reproduced approximately 2. conclude excellent overall fit provides strong evidence for existence preformed particles moving orbits large global quantum number.
