Recent studies showed that neutron pickup makes a substantial contribution to the proton optical model potential (OMP) for light, mostly halo, target nuclei. Here, we extend those studies to a more “normal” target nucleus: 40Ca. We present coupled reaction channel (CRC) calculations with the coupling of 30.3 MeV incident protons to deuterons and up to 12 states of 39Ca. The proton elastic scatt...

A broadband proton-proton-decoupled CPMG-HSQMBC method for the precise and direct measurement of long-range heteronuclear coupling constants is presented. The Zangger-Sterk-based homodecoupling scheme reported herein efficiently removes unwanted proton-proton splittings from the heteronuclear multiplets, so that the desired heteronuclear couplings can be determined simply by measuring frequency...

Introduction: One crucial point when calculating the distribution of doses with ions is the uncertainty of the Bragg peak. The proton ranges in determined geometries like homogeneous phantoms and detector geometries can be calculated with a number of various parameterization models. Several different parameterizations of the range-energy relationship exist, with different level...

Introduction The growing availability of high-field whole body scanners has generated increasing interest in non-proton in vivo spectroscopy, and with it, multinuclear RF coil design. In most non-proton applications, simultaneous or sequential operation at the proton frequency is required as well; proton decoupling, scout imaging, and polarization transfer methods are cases where transmission/r...

introduction today, there is a growing interest in the use of hadrontherapy as an advanced radiotherapy technique. hadrontherapy is considered a promising tool for cancer treatment, given its high radiobiological effectiveness and high accuracy of dose deposition due to the physical properties of hadrons. however, new radiation modalities of dose delivery and on-line beam monitoring play crucia...

conclusions the occurrence of he is associated with hyponatremia and ppi use in patients with aclf. results in univariate analysis, patients with he in aclf had a significantly higher rate of ppi use (89.1%) compared with non-he (63.6%, p = 0.001). in addition, clinical and standard laboratory variables were significantly different between the two groups regarding the infection rate, hyponatrem...

objective(s):pantoprazole, is a proton pump inhibitor (ppi) prescribed for the treatment of upper gastrointestinal disorders, which in high doses has been suggested to decrease calcium absorption leading to hypocalcaemia and therefore osteoporosis. the aim of this study was to assess whether pantoprazol, could alter the rate of orthodontic tooth movement (otm) in rats. materials and methods: a ...

A search for forward proton scattering in association with light-by-light mediated by an axion-like particle is presented, using the ATLAS Forward Proton spectrometer to detect scattered protons and central detector pairs of outgoing photons. Proton-proton collision data recorded 2017 at a centre-of-mass energy $\sqrt{s} = 13$ TeV were analysed, corresponding integrated luminosity 14.6 fb$^{-1}...

Internal target experiments with high quality proton beams allow for a new class of experiments providing null tests of time reversal symmetry in forward scattering. This could yield more stringent limits on T-odd P-even observables. A excellent candidate for such experiments is the proton deuteron system. This system is analyzed in terms of eeective T-violating P-conserving nucleon-nucleon int...

The simultaneous fit of proton ratio μpGEp/GMp, qF2p/F1p to the recent experimental data and static properties of the nucleon is studied within a light-front model with different spin coupling schemes and wave functions. The position of the zero of proton electric form factor is sensitive to the presence of a hard constituent quark component in the nucleon wave function. The fitting of the new ...
