Theory of Scattering of Protons by Protons

Physical Review, 1936
The experiments of Tuve, Heydenburg and Hafstad and those of White are discussed by means of the standard theory of scattering in central fields. The theoretical formulas are presented in a form convenient for numerical computation and are supplemented by tables.

Proton–proton correlations observed in two-proton radioactivity of 94Ag

Nature, 2006
The stability and spontaneous decay of naturally occurring atomic nuclei have been much studied ever since Becquerel discovered natural radioactivity in 1896. In 1960, proton-rich nuclei with an odd or an even atomic number Z were predicted to decay through one- and two-proton radioactivity, respectively.

Proton–Proton and Proton–Antiproton Colliders

Reviews of Accelerator Science and Technology, 2014
In the last five decades, proton–proton and proton–antiproton colliders have been the most powerful tools for high energy physics investigations. They have also deeply catalyzed innovation in accelerator physics and technology. Among the large number of proposed colliders, only four have really succeeded in becoming operational: the ISR, the SppbarS ...

The Scattering of Protons by Protons

Physical Review, 1936
Our measurements of proton-proton scattering during 1936 established the existence of large nuclear forces between protons at close distances, in addition to the usual Coulomb forces. These nuclear forces give rise to scattering in excess of the Coulomb prediction, appreciable at 700 kilovolts and very marked at 900 kv. In the energy region between 200

Proton-proton bremsstrahlung

AIP Conference Proceedings, 1978
A field theoretic calculation of ppγ is presented. Strong interactions are taken into account to second order. Apart form the contribution of OBE external exmission, the contributions of the ω‐radiative‐decay process and Δ excitation are calculated.

The scattering of protons by protons and the meson field of the proton

Physica, 1948
Abstract New calculations are made on the scattering of protons by protons with several values of the potential energy of the proton, this energy being assumed to be the meson potential. The results of these calculations are compared with the available experimental material.

Proton Migration and Tautomerism in Protonated Triglycine

Journal of the American Chemical Society, 2001
Proton migration in protonated glycylglycylglycine (GGG) has been investigated by using density functional theory at the B3LYP/6-31++G(d,p) level of theory. On the protonated GGG energy hypersurface 19 critical points have been characterized, 11 as minima and 8 as first-order saddle points.
