| 41. | For example, atomic electrons can exist in excited states and even the atomic nucleus can have excited states as well.
|
| 42. | For the rest of his career Kaluza continued to produce ideas about relativity and about models of the atomic nucleus.
|
| 43. | His theoretical discovery concerned strong force, which acts in an atomic nucleus between the quarks inside the proton and the neutron.
|
| 44. | Like NMR spectroscopy, M�ssbauer spectroscopy probes tiny changes in the energy levels of an atomic nucleus in response to its environment.
|
| 45. | He studied under Lord Ernest Rutherford, the Nobel Prize Laureate who had gained acclaim for the discovery of the atomic nucleus.
|
| 46. | That process is the reverse of " annihilation to one photon " allowed in the electric field of an atomic nucleus.
|
| 47. | At that difficult time Nikolay Semyonov and Pyotr Kapitsa, discovered a way to measure the magnetic field of an atomic nucleus.
|
| 48. | However, the neutrons in the tritium nucleus increase the attractive strong nuclear force when brought close enough to another atomic nucleus.
|
| 49. | The extra dimensions in the Berkeley theory would still be much smaller than an atomic nucleus, but larger than compactified dimensions.
|
| 50. | Some of the alpha particles of a defined energy are backscattered to the detector if they collide with an atomic nucleus.
