Carbon burning rates on the compound nucleus formation

Dissipative Collision and Compound-nucleus Formation

The successes, limitations and generalizations of transport theories for dissipative heavyion collisions are reviewed. The evolution of the collision complex can be divided roughly into three stages : nutual approach of the nuclei, local equilibration and slow relaxation of macroscopic degrees of freedom. In particular, the last stage has been thoroughly investigated within the framework of tra...

Nuclear Reaction Rates and Carbon Star Formation

We have studied how the third dredge-up and the carbon star formation in low-mass Asymptotic Giant Branch stars depends on certain key nuclear reaction rates. We find from a set of complete stellar evolution calculations of a 2M⊙ model with Z = 0.01 including mass loss, that varying either the N(p, γ)O or the triple-α reaction rate within their uncertainties as given in the NACRE compilation re...

Ellipsoidal shape fluctuations of the compound nucleus

Hot rotating compound nuclei are modeled as ellipsoidally shaped liquid drops. A formalism for the determination of their equilibrium shape distribution is presented. Commonly used metrics associated with the volume element in deformation space are derived with a discussion of their underlying assumptions. Example calculations of shape distributions are presented. These distributions are not ch...

Reaction Rates for Dense Matter Burning

Karl-Ludwig Kratz Universität Mainz Email: [email protected] An interesting question in nuclear astrophysics is the fate of post X-ray burst matter. Once an accreting neutron star has undergone thermonuclear runaway, the ashes of the burst are forced down into the crust of the neutron star. With increasing density a volume element of matter undergoes a number of electron captures and neutron...
