“…C R and R t are free parameters, which are independent of fragments. C R and R t can be easily determined from the isotopic distribution, and a constant 8 MeV is adopted to avoid excessively large values arising from the exponential term [16,18]. By considering that one has two reactions, R1 and R2, and in them one has two fragments, X1 and X2, one can define the ratio between the cross sections of X1 to X2 in the two reactions.…”

An empirical formula is proposed for predicting the cross sections of fragments in a spallation reaction. The cross sections of fragments measured in the 300, 500, 750, 1000 and 1500 MeV u−1 56Fe + p spallation reactions are analysed. The mass and incident energy dependence of the isotopic yield have been considered in the empirical formula. The cross sections of fragments predicted by the proposed empirical formula and the spallation residue cross section (spacs) parameterizations have been compared to the experimental results, showing that both of them can predict the results well. The cross sections of fragments in the 1000 MeV u−1 136Xe + p reactions can also be predicted by the proposed formula, while the spacs parameterizations significantly underestimate the measured results. The empirical formula is useful for predicting the yield of radioactive nuclei produced in proton therapy.

“…n 2 Now we are presenting a comparison of our theoretical values with experimental values in figures 23 and 24. The staggering between the even-A and odd-A nuclei appears in our studies. The previous experimental and theoretical studies related to staggering are available in [68][69][70][71][72][73][74][75]. For a detailed study, you can explore the provided references.…”

In this paper, we investigated the shape evolution and ground-state properties of 108−144I isotopes using Hartree–Fock-Bogoliubov Model while employing the axially deformed single-particle harmonic oscillator basis for the expansion of quasiparticle wave functions. We have used SKP and UNEDF2 models to perform the theoretical calculations. We have presented the shape evolution and final values of the quadrupole deformation parameter β 2 of iodine isotopes. We have used the final values of the β 2 for studying the ground-state properties of the iodine isotopic chain. The investigated ground-state properties are the nuclear electric quadrupole moment, single-particle energy levels, the binding energy per nucleon, pairing energy, one-neutron separation energy, two-neutron separation energy, nuclear charge radius, neutron rms radius, proton rms radius, and neutron skin thickness. After using the SKP parameterization on 109I, we have observed the shape coexistence of prolate and oblate shape. Similarly, after using the UNEDF2 parameterization on 110I, 112I, 114I, 115I, 116I, 117I, 118I, and 119I, we discover the shape coexistence of prolate and oblate shape.

“…Since the fragments are produced in the kinetic reaction, it is necessary to develop microkinetic models for studying the formation of fragments [19][20][21]. Some of the existing models are based on statistical descriptions of multi-body phase space calculations [22][23][24][25][26] and others are molecular dynamics models [27][28][29] or stochastic mean field models [30,31] that describe the dynamical evolution of the system in the nuclear collision.…”

Within the framework of the isospin-dependent quantum molecular dynamics model along with the GEMINI model, the reaction of 86 Kr+ 181 Ta at 80,120 and 160 MeV/nucleon and the reaction of 78 Kr+ 181 Ta at 160 MeV/nucleon are studied, and the production cross sections of the generated fragments are calculated. More intermediate and large mass fragments can be produced in the reaction with a large range of impact parameter. The production cross sections of nuclei such as the isotopes of Si and P generally decrease with the increasing incident energy. The isotopes near the neutron drip line are produced more in the neutron-rich system 86 Kr+ 181 Ta.
