AtomicAndPhysicalConstants

AtomicAndPhysicalConstants is a package which provides numerical constants and simulation-ready objects for tracking through an accelerator lattice, as well as other possible scenarios. It includes information about a number of hadrons and fundamental particles, listed below; also included is detailed information about every isotope of every atomic element documented by NIST.

The numerical constants are:

• c_light: speed of light
• h_planck: Planck's constant
• h_bar_planck: Planck's constant / 2pi
• mu_0_vac: vacuum permeability
• eps_0_vac: vacuum permittivity
• fine_structure: fine structure constant
• N_avogadro: Avogadro's constant
• m_electron: electron mass
• r_e: electron radius
• anom_mag_moment_electron: anomalous magnetic moment of the electron
• m_proton: proton mass
• r_p: proton radius
• anom_mag_moment_proton: anomalous magnetic moment of the proton
• m_neutron: neutron mass
• anom_mag_moment_neutron: anomalous magnetic moment of the neutron
• m_muon: muon mass
• anom_mag_moment_muon: anomalous magnetic moment of the muon
• m_helion: Helion (He3 nucleus) mass
• anom_mag_moment_He3: anomalous magnetic moment of the helion
• m_deuteron: deuteron mass
• anom_mag_moment_deuteron: anomalous magnetic moment of the deuteron
• m_pion_0: mass of a neutral pion
• m_pion_charged: mass of a charged pion
• kg_per_amu: mass conversion factor between kg and dalton
• eV_per_amu: mass conversion factor between eV/c^2 and dalton

Subatomic particles included with information about charge, mass, anomalous magnetic moment, and spin are:

• photon
• pion0
• pion+
• pion-
• muon
• antimuon
• electron
• positron
• proton
• anti-proton
• neutron
• anti-neutron
• deuteron
• anti-deuteron

In addition, a collection of all the isotopes documented by NIST is included. Values may be updated with setIsos()
