Siegbahn Beta- & Gamma-Ray Spectrosc. x. 301 Sn will be called the ‘shape factor’... Whenever Sn happens to be independent of the energy W,..the spectrum has the ‘statistical shape’ ∼ pW(Wo—W)2, modified only by the Coulomb effect. 1970 Physical Rev. C. 1 644/1 It is important that the correlation coefficients and the energy dependence of the shape factor be known to an accuracy of a few percent to provide a meaningful test of nuclear models. < as lemmas |
