On the Validity of the Geiger-Nuttall Alpha-Decay Law and its Microscopic Basis

摘要: a b s t r c The Geiger-Nuttall (GN) law relates the partial α-decay half-life with energy of escaping α particle and contains for every isotopic chain two experimentally determined coefficients. expression is supported by several phenomenological approaches, however its coefficients lack fully microscopic basis. In this paper we will show that: (1) empirical that appear in GN have deep physical meaning, (2) successful within restricted experimental data sets available so far, but not valid general. We that, when dependence logarithm values formation probability on neutron number linear or constant, broken. For decay neutron-deficient nucleus
