Enhanced α α-particle production from fusion evaporation reactions leading to ⁴⁶Ti

Production ofHalothermotolerant α-Amylase from aModerately Halophilic Bacterium, NesterenkoniaStrain F.

Production of extracellular amylase was demonstrated under conditions of high salinity in aerobically cultivated culture of a newly isolated moderately halophilic Gram-positive coccus, designated strain F in basal medium containing peptone from meat, yeast extract, NaCl (7% w/v) and starch. Biochemical and physiological characterization along with 16S rRNA sequence analysis placed F in the genu...

PRODUCTION OF A = 6,7 NUCLIDES IN α + α REACTIONS and COSMIC RAY NUCLEOSYNTHESIS

Roper excitation in ⃗p + α → ⃗p + α + X reactions

We calculate differential cross sections and the spin transfer coefficient D nn in the p+α → p+α+π 0 reaction for proton bombarding energies from 1 to 10 GeV and π 0 − p invariant masses spanning the region of the N * (1440) Roper resonance. Two processes – ∆ excitation in the α-particle and Roper excitation in the proton – are included in an effective reaction model which was shown previously ...

Internalized Α-particle Emitting Radionuclides

Radon is a natural radioactive gas produced by the decay of uranium and thorium, which are present in all rocks and soils in small quantities. There are several isotopes of radon, the most important of which are 222Rn (produced from 238U) and 220Rn (produced from thorium). 220Rn is also known as thoron because of its parent radionuclide. In the United Kingdom, it has been shown that 220Rn deliv...
