a) On average, the speed of the atoms is twice the speed of the atoms at 60 K.

- I think that the electrons that are emitted from the cathode are emitted with a range of velocities (perhaps like a Boltzmann distribution where average speed clusters in the middle of the range).

%The invariant mass of the electron pair, evaluated via the energy-momentum four-vectors at the beam pipe,

Elizabeth Gibney discusses the history of fast radio bursts and astronomer’s strategy to finding them in the universe in her article, “Fast Radio Bursts are Astronomy’s Next Big Thing.” She begins by defining fast radio bursts as “fleeting blasts of energetic cosmic radiation of unknown cause.” (Gibney) Gibney briefly reviles that even though FBRs were discovered a decade ago, the phenomenon has just recently been accepted as genuine.

1. What is the difference between a hypothesis and a theory? (Pages 2 – 3)

Before Rutherford’s Geiger-Marsden experiment the most popular model of the atom was the “plum pudding model” developed in 1904 by the person who also discovered the electron in 1897, J.J. Thompson. It was the most common model of the atom and stated that electrons (plum) floated around with

An accurate description of atomic processes governing the origin of elements in the astronomical objects is essential to understand the cosmic evolution of the universe. This project is one of the endeavors to accomplish this goal. Also, the knowledge of the atomic structure of heavy elements such as Krypton, Xenon, and Molybdenum is necessary to understand their interaction with the plasma in power generation reactors. New S2+ DR results may remove the anomalous behavior noticed by plasma modelers in its elemental abundance observed in the Orion Nebulae. Most importantly, this work will make my contribution as a woman in this male-dominating field and will inspire other women and me to take advantage of every opportunity come across to give

Figure 3.2 was created using modified code from the Eagle Space Flight Team. The modified code is not included in Appendix I because it contains many sub functions and would make the length of this lab longer than 20 pages. The code is available upon request by emailing Carl Leake at leakec@my.erau.edu.

The particles started to move around more and gained kinetic energy. They were also staring to spread apart more.

Since the electrons are stripped from the atoms in a plasma, all that remains is the positively charged nucleus, which can be acted on by magnetic fields. In magnetic confinement reactors, so-called magnetic bottles are created with magnetic fields that confine the plasma. In experiments, however, plasmas can only be contained for a few seconds before their oscilations cause them to come into contact with the walls of the reactor. The biggest problem in controlling plasmas with magnetic confinement is their chaotic behaivior. With continuing research, longer containment times are being recorded.

Most of the problems to which the author refers to constitute very recent research problems in the field of space plasma, and the book contains at the end a very rich list of important references on the field, that the author uses along the whole book.
