Abstract:Comparison of non-unitary and generalized unitary scattering theories is done by means of nuclear monodromy (equivalence of Schrödinger and Maxwell time-independent equations), tunneling and radioactivity. Radioactivity is important part of physics and our life. Its importance stretches from medicine as far as to war strategies. We present theoretical approach to achieve better understanding of the radioactive decay when modified quantum theory is applied. It can be done by updating existing codes to understand better construction of the world and terms and conditions of our existence. The theory modifications are strictly connected with the unimodular M matrix and Wronskian matrices (i.e. their determinants named Wronskians) which create underpinning of so called monodromy being two track wave-function evolution.
