“…Using the same method as for 22 C we determine the neutron radius of 20 C and 19 C to be 3.58±0.16 fm and 3.49± 0.12 fm, respectively. These values are in good agreement with [25,27]. Assuming that the proton radius of 20,19 C is 2.33 fm (same as 12 C) the neutron skin thickness of 20 C and 19 C are evaluated to be 1.25±0.16 fm and 1.16±0.12 fm, respectively.…”

“…The use of HO density was dictated by the wish to compare our results to those in the existing literature. We repeated our calculations for 22 C and 14 Be using Woods-Saxon type densities as in [27]. Consequently, the neutron radii of 22 C and 14 Be were determined to be 5.27±0.93 fm, and 3.4±0.12 fm, respectively.…”

“…It has been shown, in [27], that various nuclear density distributions having the same matter radii provide almost the same values of the p-nucleus reaction cross section in the energy region 100A-800A MeV. Furthermore, charge radii obtained from the isotope-shift technique show that the maximum difference between the measured charge radii of the isotopes of the same element for 4,6,8 He, 6,8,9,11 Li, [9][10][11] Be, and [24][25][26][27][28][29][30][31][32] Mg are 0.392±0.019 fm (23% from that of 4 He) [11], 0.3±0.065 fm (12% from that of 6 Li) [13], 0.162±0.03 fm (6% from that of 9 Be) [14], and 0.158±0.008 fm (5% from that of 24 Mg) [16], respectively. Also, the proton radii obtained from the charge-changing cross section indicate that the maximum difference between the measured proton radii of the isotopes of the same element for [12][13][14][15][16][17] B, [12][13][14][15][16] C, and [12][13][14][15][16]…”

A new method is proposed to deduce the neutron radii of neutron-rich nuclei. This method requires measuring the reaction cross sections of both the neutron-rich nucleus and its stable isotope at the same energy on a proton target.Neutron halo structure has been observed among the neutron-rich nuclei, it is manifested by the neutron density extending to extraordinary large radial distance. The neutron halo structure is indicated first by an increase in the root-mean-square point matter radii (matter radii) [1]. The matter radii (r m = r 2 m 1/2 ) of unstable nuclei are usually calculated by measuring their reaction (interaction) cross sections on Carbon target [1] or proton target [2] by the Glauber theory.

“…Ion beam contamination due to projectile's isotopes is one of the major and longstanding experimental issues that must be considered [25], which hinders the measurement. Kozma et al [26] and Kaki [27] attempted to measure the production cross-section of these projectile's isotopes for different interactions. This study estimated the production cross-sections of projectile's isotopes for 12 C and 4 He ion beams in different media with the Monte Carlo calculation by Particle and Heavy Ion Transport code System (PHITS) [28].…”

Background: Isotopes of the projectile may be produced along the beam path during the irradiation of a target by a heavy ion due to inelastic interactions with the media. This study analyzed the production cross-section of carbon (C) and Helium (He) projectile’s isotopes resulting from the interactions of these beams with different materials along the beam path.Materials and Methods: In this study, we transport C and He ion beams through different materials. This transportation was made by the Monte Carlo simulation. Particle and Heavy Ion Transport code System (PHITS) has been used for this calculation.Results and Discussion: It has been found that 10C, 11C, and 13C from the 12C ion beam and 3He from the 4He ion beam are significant projectile’s isotopes that have higher flux than other isotopes of these projectiles. The 4He ion beam has a higher projectile’s isotope production cross-section along the beam path, which adds more impurities to the beam than the 12C ion beam. These projectile’s isotopes from both the 12C and 4He ion beams have higher production cross-sections in hydrogenous materials like water or polyethylene.Conclusion: It is important to distinguish these projectile’s isotopes from the primary beam particles to obtain a precise and accurate cross-section result by minimizing the error during measurement with a nuclear track detector. This study will show the trend of the production probability of projectile’s isotopes for these ion beams.

We present a systematic study of the 10−14 C isotopes within the ab initio no-core shell model theory. We apply four different realistic nucleon-nucleon (NN) interactions: (i) the charge-dependent Bonn 2000 (CDB2K) potential (ii) the inside non-local outside Yukawa (INOY) potential (iii) the next-to-next-to-next-to-leading order (N 3 LO) potential, and (iv) the optimized next-to-next-toleading order (N 2 LOopt) potential. We report the low-lying energy spectra of both positive and negative parity states for the 10−14 C isotopes and investigate the level structures. We also calculate electromagnetic properties such as transition strengths, quadrupole and magnetic moments. The dependence of point-proton radii on the harmonic oscillator frequency and basis space is shown. We present calculations of the translation invariant one-body density matrix in the no-core shell model and discuss isotopic trends in the density distribution. The maximum basis space reached is 10 Ω for 10 C and 8 Ω for 11−14 C, with a maximum M-scheme dimension of 1.3 × 10 9 for 10 C. We found that while the INOY interaction gives the best description of the ground state energies, the N 3 LO interaction best reproduces the point-proton radii.
