Nuclear transparency to intermediate-energy protons

Nuclear transparency to intermediate-energy protons.

Nuclear transparency in the (e, e′p) reaction for 135 ≤ Tp ≤ 800 MeV is investigated using the distorted wave approximation. Calculations using densitydependent effective interactions, both empirical and theoretical, are compared with phenomenological optical potentials. We find that nuclear transparency is well correlated with proton absorption and neutron total cross sections and that calcula...

Energy dependence of nuclear transparency in C (p,2p) scattering.

The transparency of carbon for (p,2p) quasielastic events was measured at beam momenta ranging from 5.9 to 14.5 GeV/c at 90 degrees c.m. The four-momentum transfer squared (Q2) ranged from 4.7 to 12.7 (GeV/c)(2). We present the observed beam momentum dependence of the ratio of the carbon to hydrogen cross sections. We also apply a model for the nuclear momentum distribution of carbon to obtain ...

A new idea “ nugget ” from FOCUS : Nuclear activation with high - energy protons

This document contains this year’s “ingot” of nuggets from FOCUS. I hope you enjoy them. Each nugget is self-contained, and (we hope) written with for the interested non-specialist. Here are the subjects of this year’s contributions: 1. Laser-induced proton activation of radionucleides 2. High resolution non-linear spectroscopy in a cold atomic gas 3. Trapping Cavitation Bubbles with Self-Focus...
