- An electron-positron system is in n=2n=2 state. (a) Find the ionization energy (energy required to free the electron off the hold of positron) and the radius of the orbit. Interpret this radius in the context of the electron-positron system. (b) Compare the radius found in above with an estimate coming from uncertainty principle. (c) Find the wavelength of the photon emitted when the system decays to its ground state. (d) How much do the results change in the above if electron mass is used instead of the reduced mass for the system? (e) Is the system a relativistic system? Support your answer with an appropriate calculation. NOTE: (1) Positron is the antiparticle of electron. It has the same mass as that of an electron but opposite electric charge with the same magnitude. (2) Use reduced mass unless asked otherwise.arrow_forwardThe reaction 9Be (3H, p) 11Be is studied by bombarding 9Be with 5 MeV tritons.Protons with energies of 2.260, 1.967 and 0.620 MeV are observed at 90 ° of the incident beam due to the formation of 11Be in the ground state and in two excited states:(a) Find the atomic mass of 11Be.(b) Find the excitation energy of the excited states.arrow_forwardThe nuclear radii of aluminum and gold are approximately r = 3.6 fm and 7.0 fm, respectively. The radii of protons and alpha particles are 1.3 fm and 2.6 fm, respectively. (a) What energyα particles would be needed in head-on collisions for the nuclear surfaces to just touch? (This is about where the nuclear force becomes effective.) (b) What energy protons would be needed? In both (a) and (b), perform the calculation for aluminum and for gold.arrow_forward
- The positron has charge +e and mass equal to the electron mass. Calculate in electronvolts the ground- state energy of positronium-an "atom" that consists of a positron and an electron. Consider a positronium as a hydrogenlike atom with reduced mass μ = meme /(me + me). -6.8 eV O None of the given choices. -185 eV O-13.6 eV O 3.69 eVarrow_forwardPositronium consists of an electron and a positron (same mass, opposite charge) orbiting round their common centre of mass. The broad features of the spectrum are therefore expected to be hydrogen-like, the differences arising largely from the mass differences. Predict the wavenumbers of the first three lines of the Balmer series of positronium.

- True or False 1. Gamma radiation is stronger than infared radiation because it has a much lower frequency. 2. A blue shirt appears blue because the fabric is dyed with a color that absorbs all of the blue light. 3. A solution that appears orange will absorb light at the 450-490nm range. 4. UV-Vis spectroscopy is necessary for the analysis of organic compound because most organic compounds are colored green in the presence of an extracting solvent. 5. The spectrophotometer is able to detect and report absorbance values of a compound based on the compound's ability to absorb radiation or emit radiation. 6. A common electronic transition for an organic compound is the electron shifting from a bonding orbital to a nonbonding orbital. 7. UV-Vis spectroscopy normally reports data in the form of bands rather than single peaks because of overlapping electronic transitions that are being recorded by the detector. 8. When using linear regression to translate absorption data using Beer's law,…arrow_forwardProfessor E. Lawrence suggested that to separate Uranium-235 from Uranium-238 a mass spectrograph could be used. The mass of a Uranium-235 atom is given by.
