A new apparatus in nuclear physics for the investigation of β- and γ-rays. Part II
AgCl crystals were irradiated with monochromatic β-rays in a magnetic β-ray spectrograph. The results show that under suitable experimental conditions in the crystal all β-rays of a certain energy cause ionisation pulses of the same value within the errors of measurement. The magnitude of an ionisat...

AgCl crystals were irradiated with monochromatic β-rays in a magnetic β-ray spectrograph. The results show that under suitable experimental conditions in the crystal all β-rays of a certain energy cause ionisation pulses of the same value within the errors of measurement. The magnitude of an ionisation pulse is proportional to the energy of the β-particle. This means that the amount of energy necessary for the formation of one conduction electron is independent of the energy of the β-rays. This amount was found to be 7,6 eV.The measurements of the ionization pulses caused in AgCl by α-rays showed that many of the α-particles caused an ionization pulse smaller than normal. We ascribed this effect to a thin irregular surface layer which is less effective than the crystal's interior. Many of the crystals we investigated showed a thicker surface layer. This layer also influenced the ionization by β-particles, which then showed the same effect as the α-rays. The nature and the circumstances under which this hypothetical surface layer appears or can be removed are not yet clear and still form a point of investigation. |

The results show that under suitable experimental conditions in the crystal all β-rays of a certain energy cause ionisation pulses of the same value within the errors of measurement. The magnitude of an ionisation pulse is proportional to the energy of the β-particle. This means that the amount of energy necessary for the formation of one conduction electron is independent of the energy of the β-rays. This amount was found to be 7,6 eV.The measurements of the ionization pulses caused in AgCl by α-rays showed that many of the α-particles caused an ionization pulse smaller than normal. We ascribed this effect to a thin irregular surface layer which is less effective than the crystal's interior. Many of the crystals we investigated showed a thicker surface layer. This layer also influenced the ionization by β-particles, which then showed the same effect as the α-rays. The nature and the circumstances under which this hypothetical surface layer appears or can be removed are not yet clear and still form a point of investigation.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Elsevier Journal Backfiles on ScienceDirect 1907 - 2002</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Van Heerden, P.J.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Milatz, J.M.W.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">in</subfield><subfield code="t">Physica</subfield><subfield code="d">Amsterdam : Elsevier</subfield><subfield code="g">16(1950), 6, Seite 517-527</subfield><subfield code="w">(DE-627)NLEJ177041110</subfield><subfield code="w">(DE-600)2205782-1</subfield><subfield code="x">0031-8914</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:16</subfield><subfield code="g">year:1950</subfield><subfield code="g">number:6</subfield><subfield code="g">pages:517-527</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://dx.doi.org/10.1016/0031-8914(50)90008-5</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_H</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-SDJ</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">16</subfield><subfield code="j">1950</subfield><subfield code="e">6</subfield><subfield code="h">517-527</subfield></datafield></record></collection>
