Role of momentum in the generator-coordinate method applied to barrier penetration

K. Hagino, G. F. Bertsch

Nuclear fission at barrier-top energies is conventionally modeled by a one-dimensional Schrödinger equation applied to internal fission channels, but that treatment is hard to just…

Non-equilibrium Green's function approach to low-energy fission dynamics: fluctuations in fission reactions

K. Uzawa, K. Hagino

We present a microscopic modeling for a decay of a heavy compound nucleus, starting from a nucleonic degree of freedom. To this end, we develop an approach based on a non-equilibri…

Barrier penetration in a discrete-basis formalism

G. F. Bertsch, K. Hagino

The dynamics of a many-particle system are often modeled by mapping the Hamiltonian onto a Schrödinger equation. An alternative approach is to solve the Hamiltonian equations direc…

Barrier penetration in a discrete basis formalism

K. Hagino

A standard way to solve a Schrödinger equation is to discreteize the radial coordinates and apply a numerical method for a differential equation, such as the Runge-Kutta method or…

Modeling barrier-top fission dynamics in a discrete-basis formalism

G. F. Bertsch, K. Hagino

A configuration-interaction model is presented for the barrier region of induced fission. The configuration space is composed of seniority-zero configurations constructed from self…

Diabatic Hamiltonian matrix elements made simple

K. Hagino, G. F. Bertsch

With a view to applying the Generator Coordinate Method to large configuration spaces, we propose a simple approximate formula to compute diabatic many-body matrix elements without…
