Proton radioactivitylifetimesProton radioactivity of neutron-deficient nuclei with atomic numbersZ=51–91 and mass number 104–211 is investigated using the analytical super-asymmetric fission (ASAF) model — a model used to studyα-decay and cluster radioactivity since 1984. The experimentalQpvalues ...

The number of transistors increased from 2,300 in 1971 to 1.5 billion in 2015. Today, computer processors, such as the recently announced Apple A12 Bionic chip and Huawei Kirin 980, use 7 nm processes with 6.9 billion transistors on a centimeter square chip. The limits are being pushed to ...
Within the single-particle picture, a parabolic confinement potential along the nanotube leads to a ladder of harmonic oscillator levels, whose wavefunctions’ extent along the nanotube axis increases with increasing level number (Fig. 1a, gray illustrations). Each level is 4-fold degenerate, due ...
(Fig.5c). The overall pattern ofτc-values with respect to residue number remains the same at each NaCl concentration, with maxima at L3-F4, and Q9-A11, and an increase in salt concentration results in an increased τcfor each residue. The relative increase in τcis similar throughout ...
Chemical properties would thus have to depend on the number and constellations of these corpuscles inside the atom. They would have to have stable positions in it, bound by electrostatic and possibly kinetic forces. Because under normal conditions chemical atoms are electrically neutral, the total ...
