Studying Heavy-ion Reactions using the Mass- Angle Distribution (MAD) Technique
نویسندگان
چکیده
Super-heavy elements [1] can only be formed by fusing two massive nuclei. These elements are predicted to be stabilised by nuclear shell effects associated with near-spherical shapes around new predicted neutron and proton magic numbers. Their cross section of formation is inhibited by several orders of magnitude by the premature breakup of the elongated di-nuclear system known as quasi-fission [2,3]; and by fission of the unstable compound nucleus after fusion.

Modeling Magnetic Field in Heavy ion Collisions Using Two Different Nuclear Charge Density Distributions
By studying the properties of matter during heavy-ion collisions, a better understanding of the Quark-Gluon plasma is possible. One of the main areas of this study is the calculation of the magnetic field, particularly how the values of conductivity affects this field and how the field strength changes with proper time. In matching the theoretical calculations with results obtained in lab, two diffe...
متن کاملImpact of Various Beam Parameters on Lateral Scattering in Proton and Carbon-ion Therapy
Background: In radiation therapy with ion beams, lateral distributions of absorbed dose in the tissue are important. Heavy ion therapy, such as carbon-ion therapy, is a novel technique of high-precision external radiotherapy which has advantages over proton therapy in terms of dose locality and biological effectiveness.Methods: In this study, we used Monte Carlo method-based Geant4 toolkit to s...
متن کاملMetastable atom-activated dissociation mass spectrometry of phosphorylated and sulfonated peptides in negative ion mode.
The dissociation behavior of phosphorylated and sulfonated peptide anions was explored using metastable atom-activated dissociation mass spectrometry (MAD-MS) and collision-induced dissociation (CID). A beam of high kinetic energy helium (He) metastable atoms was exposed to isolated phosphorylated and sulfonated peptides in the 3- and 2- charge states. Unlike CID, where phosphate losses are dom...

We discuss the effects of fast nuclear excitations on heavy-ion fusion reactions at energies near and below the Coulomb barrier. Using the fusion of two 40 Ca nuclei as an example and the inversion method, we show that the mass renormalization induced by fast nuclear excitations leads to a large surface diffuseness in the effective potential for heavy-ion fusion reactions.

The recent investigations show that the size and mass number of the target nucleus in the heavy-ion fission reactions are very important for the angular distribution of fission fragments. In this work, we consider the behavior of fission fragment angular anisotropies within the standard saddle-point statistical model for the 168O, 188O, 199F, 2412Mg, 2814Si, 32 16 S+20882Pb fission reaction sy...
