Setting Legal Norms in the Netherlands for the Implementation of EU Law, Summary of Ph.D. Thesis

Compilation of giant electric dipole resonances built on excited states

“…A first good understanding of statistical γ emission was gained from the works of Brink [1] and Axel [2] who realized that average electric-dipole (E1) transition strengths in different energy regimes can be described in a unified fashion by assuming that the GDR can be built on any excited state, and that the GDR properties do not depend on the temperature of the excited state in question.…”

A unified understanding of (γ, n) and (n, γ) reactions and direct neutron-multiplicity sorting

“…(2), (3), and (4) to obtain N 1 , N 2 , and N 3 from which σ (γ, n), σ (γ, 2n), and σ (γ, 3n) are determined from Eq. (1).…”

“…In the statistical model, the (γ ,n) and (n,γ ) reaction cross sections are interconnected through the γ SF and the Brink hypothesis linking the downward γ SF in photo-deexcitation to the upward γ SF in photoabsorption in the approximate equality [1]. An indirect method called the γ -ray strength function method [2] was devised for constraining radiative neutron capture cross sections for unstable nuclei of direct relevance to nuclear astrophysics and nuclear engineering.…”

Measurement of theMo97(n,γ)reaction with the DANCEγcalorimeter array

“…The parameter T in Eq. (1) represents the nuclear temperature, as f (GLO) E1 depends on T (or equivalently on excitation energy) which implies that the Brink hypothesis [29], which assumes that the PSF is independent of initial and final states and is only a function of E γ , is not valid in its strict form.…”
