انحلال نواة Cd 115m Decay of 115m Cd

Abstract

تتحلل نواة Cd 115m إلى نواة In 115 عن طريق الانبعاث البائي السالب بالإضافة إلى ملاحظة 19 انتقال جامي، سبق ملاحظتهم في دراسات سابقة، فإنه تم اكتشاف انتقالين جاميين جديدين طاقتهما 60500 و 88908 KeV وتم حساب الطاقات والشدات النسبية لجميع الخطوط الملاحظة بالإضافة إلى بناء مخطط مستويات الطاقة لنواة In 115 حيث يحتوي على عشرة مستويات طاقة، كما تم تأكيد لف المستوى eV 141827 وهو 9 2

The work presented here is on the study of energy levels and transitions in the 115 In nucleus produced indecay of 115m Cd with half life of 446 d The gamma singles spectra have been measured applying modern techniques in gamma spectroscopy The detection system consisted of germanium GMX–Ge detector and conventional low noise electronics connected to a multichannel analyzer The energies and relative intensities of observed gamma transitions were determined Actual of nineteen gamma transitions in 115 in nucleus following the decay of 115mCd are reported Two lines 605 KeV and 88908 KeV are observed for the first time A level scheme of ten levels to the 115 In nucleus is constructed The spin for the level 141827 KeV has been confirmed to be 9 2 The logft values of the beta transitions feeding levels in 115 In have been calculated These values together with the corresponding gamma transitions intensities were used to confirm the spins and parities of different levels which were found to agree with previously reported values
