    Optical model analysis of scattering of 7- to MeV neutrons from 1-p shell nuclei Journal Article Dave, J H ; Gould, C R - Phys. Rev. C; (United States) An optical model analysis of results from a program of neutron time-of-flight measurements of elastic scattering from the 1-p shell nuclei is described. For the case of light alpha particles scattering off heavy nuclei, as in the experiment performed by Rutherford, the reduced mass is essentially the mass of the alpha particle and the nucleus off of which it scatters is essentially stationary in the lab frame.

Additional Physical Format: Online version: Drentje, Anne Gerben. Alpha particle scattering from 24 Mg. nuclei. Groningen, Veenstra, (OCoLC) A large enhancement is observed in the scattering cross section near a center-of-mass energy of MeV, with dominant angular momenta near L=14–16 h ̵, which could be associated with highly-deformed alpha-particle cluster configurations in 24 by: 3.

The same experiment also reveals fission into 16 O+ 12 C from states in 28 Si populated by alpha-particle pickup onto the 24 Mg projectile.

The correlation of the states in 24 Mg observed in this experiment with those previously observed in 12 C+ 12 C scattering is by: target nuclei. In the first part is describing of the general theory of particle scattering on collective states of nuclei SCMC by using the collective excitations as a state of interacting bosons.

The theory is applied to the study of the scattering of the 4GH on the ground states of light nuclei 22Ne, when the incident energy E = MeV and.

The similarity of the experimental angular dependences of the components of tensor polarizations in inelastic deuteron and 3 He scattering on 12 C nuclei, as well as in inelastic alpha-particle scattering on 24 Mg and 28 Si nuclei, was by: 3. The role of spin-orbit and tensor d 24 Mg interactions is discussed along with the influence of the reorientation effect.

The multiparticle densities of these nuclei and single-particle nucleon-distribution densities as obtained from the dispersive α-cluster model were used in the calculations. The differential cross sections and polarizations for elastic and inelastic p 20 Ne and p 24 Mg scattering at the energy of MeV are in better agreement with experimental data than the analogous calculations at the energy of MeV.

The correlation features of the 2+ state of the 24Mg nucleus at MeV that were determined in inelastic deuteron and alpha-particle scattering on 24Mg are compared. Measured and calculated angular dependences of components of the polarization tensor of a 12 C nucleus in the 2 + state at MeV formed in various reactions involving light particles, as well as 24 Mg(2 +, MeV) and 28 Si(2 +, MeV) nuclei formed in inelastic alpha-particle scattering, are experimental tensor polarization in question was reconstructed on the basis of Cited by: 3.

Alpha-gamma angular correlations have been measured at 73 scattering angles in the reaction plane for the reaction C 12 (α, α'γ ) and at 40 scattering angles for the reaction Mg 24 (α, α'γ ).Cited by: Electron Scattering from Nuclei. The scattering of electrons from nuclei has given us the most precise information about nuclear size and charge distribution.

The electron is a better nuclear probe than the alpha particles of Rutherford scattering because it is a point particle and can penetrate the nucleus.

The alpha process, also known as the alpha ladder, is one of two classes of nuclear fusion reactions by which stars convert helium into heavier elements, the other being the triple-alpha process.

The triple-alpha process consumes only helium, and produces carbon. After enough carbon has accumulated, the reactions below take place, all consuming only helium and the product of the previous reaction.

Radioactive nuclei undergoing “natural” decay emit alpha particles with energies typyp y gically in the range of 3 - 7 MeV. The β-factor (β =v/c))pp of these alpha particles is very small.

The normal activity of living carbon-containing matter is found to be about 15 decays per minute for every gram of carbon.
