Reaction 27Al

The reaction [Formula: see text]Al([Formula: see text],3He) at 25 MeV beam energy has been utilized to study the states in even–even nucleus [Formula: see text]Mg. The spectroscopic factors have been extracted for the states of [Formula: see text]Mg up to 7.50[Formula: see text]MeV excitation energy using local, zero-range distorted wave Born approximation. The extracted spectroscopic factors have been compared with the previously reported values. The present results were also compared with the predictions from a theoretical shell model and rotational model.

Approximation Analysis

Zero-range distorted-wave Born approximation calculations are used to investigate the systematics of two-nucleon transfer reactions. The shapes of the calculated 40Ca(t,p)42Ca(gs) and 208Pb(p,t)206Pb(gs) cross sections are relatively insensitive to details of the core plus two-neutron form factor, if the form factor tails have similar shapes. Studies of heavy targets such as 206Pb suggest a surface reaction mechanism, but lighter targets (16O and 40Ca) indicate that spatial regions beyond the target surface provide the dominant contribution to the (p,t) cross section.

Excited levels of 70Ge and proton holes in 69Ga have been investigated by means of the 69Ga (3He, d)70Ge reaction at an incident beam energy of 22.5 MeV. Angular distributions were measured and are compared with the prediction of the distorted-wave-Born-approximation (DWBA) theory in order to obtain the spectroscopic strengths of each level.The number of proton holes in 69Ga was obtained from the sum rule of the spectroscopic strengths. The vacancy probability UJ2 and the center of gravity energy EJ for the 2p3/2, 1f5/2, and 2p1/2 subshells are[Formula: see text]These are compared with the pairing model calculations.

Good Agreement

In this paper, the [Formula: see text] reactions are revisited, with the goal of obtaining spectroscopic factors (SF) for the transition to the ground state of some residual nuclei, applying the distorted wave Born approximation (DWBA). The double-folding São Paulo Potential (SPP) was used to derive the distorted wave function in the entrance and exit channels. The derived SF are compared with the results of extensive shell model calculations showing a rather good agreement.

The reactions 68Zn(d,6Li)64Ni(0+,g.s.) and 68Zn(d,6Li)64Ni(2+, 1.34 MeV) are investigated using the zero-range distorted wave Born approximation (ZRDWBA). ZRDWBA calculations indicate that the optical parameter set of Fulbright et al. provides a good representation of the transfer data, and that adjustments to Coulomb radii or form factor quantum numbers are not necessary. Relative strengths for the 0+ and 2+ levels are found to vary by a factor of two when reasonable changes to form factor geometries are made.

The 97 Mo (t,p)99 Mo reaction has been studied with the triton beam energy of 12 MeV obtained from tandem Van de Graaff accelerator at the Atomic Weapon Research Establishment, Aldermaston. Proton spectra were obtained at 12 different angles from 5° to 87.5° at an interval of 7.5° and were detected in nuclear emulsion plates. Angular distributions for transitions to 46 levels in the energy range from 0 to 2.054 MeV have been measured. Absolute differential cross-sections for the levels have been measured. The experimental angular distributions are compared with the distorted-wave Born approximation calculations (DWBA) to determine L and Jπ values. The present results are compared with the previous experimental results and model predictions.
