Roentgen Rays and Phenomena of the Anode and Cathode.
CHAPTER VI
ยง 65, Cathode Rays Outside of the Discharge LENARD top of Tube whose Exit is an Aluminum page Window. A Glow Outside of the Window. 53.
65., Properties of Cathode Rays in Open Air. LENARD end of page 53.
66. Phosphorescence by Cathode Rays Outside LENARD of the Discharge Tube.
66_a_. Transmission Tested by Phosphorescence.
67. The Aluminum Window a Diffuser of LENARD Cathode Rays.
68. Transmission of External Cathode Rays LENARD through Aluminum and Thinly Blown Glass.
69. Propagation of External Cathode Rays. LENARD Turbidity of Air.
70. Photographic Action by External Cathode LENARD Rays and at Points beyond the Glow. No Other Chemical Power Probable. Shadows of Objects by Light and by External Cathode Rays Compared. No Heat Produced by External Cathode Rays.
71. External Cathode Rays and the Electric LENARD Spark Distinguished. Aluminum Window Not a Secondary Cathode.
72. Cathode Rays Propagated, but Not LENARD Generated, in the Highest Possible Vacuum. Air Less Turbid when Rarefied.
72_a_. Cathode Rays, while Traversing the LENARD Exhausted Observing Tube, Deflected by a Magnet. No Turbidity in a Very High Vacuum.
72_b_. An Observing Tube for Receiving the LENARD Rays and Adapted to be Exhausted.
73. Phenomena of Cathode Rays in an LENARD Observing Tube Containing Successively Different Gases at Different Pressures. Phosphorescent Screen Employed for Making the Test.
74. Cause of the Glow Outside of the LENARD Aluminum Window. Glow Not Caused by External Cathode Rays. Sparks Drawn from the Aluminum Window. Transmission of External Cathode Rays Dependent Alone upon the Density of the Medium.
75. External Cathode Rays of Different LENARD Kinds Variably Diffused. Theoretical Observations.
76. Law of Propagation of External Cathode LENARD Rays.
77. Charged Bodies Discharged by External LENARD Cathode Rays. Discharge at Greater Distances than Phosphorescence. Not Certain as to the Discharge Being Directly Due to Intermediate Air.
78. Source, Propagation, and Direction of DE KOWALSKIE Cathode Rays. General Conclusions.
