“…In addition to the Schwartz et al [93] experiment at 7.4 MeV, the 40 Ar(α,p) 43 K reaction was also measured at higher energies by Tanaka et al [94] and Fenyvesi et al [14]. Both experiments used a stacked-target technique Cross sections of the 40 Ar(α,n) 43 Ca and 40 Ar(α,p) 43 K reactions.…”

“…Both experiments used a stacked-target technique Cross sections of the 40 Ar(α,n) 43 Ca and 40 Ar(α,p) 43 K reactions. The experimental data have been taken from [93,94,14]. The energy of the data points by Schwartz et al [93] at Eα = 7.4 MeV should be corrected by about 500 keV because of the energy loss of the beam in the entrance window of the gas target and in the gas cell.…”

“…and 4π-β-counting in [94] and γ-spectroscopy in [14] for the detection of the decay of the residual 43 K nucleus. The results of the experiments of [94,14] are in good agreement, and also the 7.4 MeV data point of Schwartz et al [93] seems roughly to follow the expected energy dependence (in particular, if the energy of this data point is corrected by about 500 keV as discussed above).…”

“…At slightly higher energies α-induced reactions are used for the production of important tracer elements. For biological and medical studies 43 K can be produced by 40 Ar(α,p) 43 K [14], and 30 P can be made from 27 Al(α,n) 30 P [15]. The behavior of aluminum in bio-and eco-systems can be traced by 29 Al which is produced by the 26 Mg(α,p) 29 Al reaction [16].…”

Abstract. A simple reduction scheme using so-called reduced energies E red and reduced cross sections σ red allows the comparison of heavy-ion induced reaction cross sections for a broad range of masses of projectile and target and over a wide energy range. A global behavior has been found for strongly bound projectiles whereas much larger reduced cross sections have been observed for weakly bound and halo projectiles. It has been shown that this simple reduction scheme works also well for α-particle induced reactions on heavy target nuclei, but very recently significant deviations have been seen for α+ 33 S and α+ 23 Na. Motivated by these unexpected discrepancies, the present study analyses α-induced reaction cross sections for targets with masses A ≈ 20 − 50. The study shows that the experimental data for α-induced reactions on nuclei with A ≈ 20 − 50 deviate slightly from the global behavior of reduced cross sections. However, in general the deviations evolve smoothly towards lower masses. The only significant outliers are the recent data for 33 S and 23 Na which are far above the general systematics, and some very old data may indicate that 36 Ar and 40 Ar are below the general trend. As expected, also the doubly-magic 40 Ca nucleus lies slightly below the results for its neighboring nuclei. Overall, the experimental data are nicely reproduced by a statistical model calculation utilizing the simple α-nucleus potential by McFadden and Satchler. Simultaneously with the deviation of reduced cross sections σ red from the general behavior, the outliers 23 Na, 33 S, 36 Ar, and 40 Ar also show significant disagreement between experiment and statistical model calculation.PACS. 25.55.-e 3H-, 3He-, and 4He-induced reactions -24.10.Pa Thermal and statistical models

“…However, as expected, the yield of the product in -particle induced reaction is lower than in the commonly used reaction. For 76 Br only the 75 As( ,3n) 76 Br reaction cross sections have been measured [174,209]. Similarly for 82m Rb only the 79 Br( ,n) 82m Rb reaction cross sections have been reported (cf.…”

Uses of alpha particles, especially in nuclear reaction studies and medical radionuclide production

et al. 2016

Alpha particles exhibit three important characteristics: scattering, ionisation and activation. This article briefly discusses those properties and outlines their major applications. Among others, -particles are used in elemental analysis, investigation and improvement of materials properties, nuclear reaction studies and medical radionuclide production. The latter two topics, dealing with activation of target materials, are treated in some detail in this paper. Measurements of excitation functions of -particle induced reactions shed some light on their reaction mechanisms, and studies of isomeric cross sections reveal the probability of population of highspin nuclear levels. Regarding medical radionuclides, an overview is presented of the isotopes commonly produced using -particle beams. Consideration is also given to some routes which could be potentially useful for production of a few other radionuclides. The significance of -particle induced reactions to produce a few high-spin isomeric states, decaying by emission of low-energy conversion or Auger electrons, which are of interest in localised internal radiotherapy, is outlined. The -particle beam, thus broadens the scope of nuclear chemistry research related to development of non-standard positron emitters and therapeutic radionuclides.
