A Novel Method of Analyzing a Reaction Using the Data from Particle and Gamma-ray Detectors

Öz

The radioactive isotope beam (RIB) of 25Na at 5MeV/u energy in maximum 3x107 pps intensity was fired on a deuterated polyethylene (CD2) to investigate mainly (d,p gamma) reaction. However, there were other reaction possibilities, which were arisen from the same collision, to be eliminated wisely. As to a particle detector and a gamma-ray detector, highly selective double-sided silicon strip detectors (DSSSD) and high purity germanium detectors (HPGe) were employed to make delicate selections of distinctive energies of experimentally populated excited states of 26Na. The motivation of this work was to show how to combine the information coming out of two different types of detectors in terms of energies to reach out a new unobserved data. This study was a part of the experiment with Silicon Highly-segmented Array for Reactions of Coulex (SHARC) and TRIUMF-ISAC Gamma-ray Escape-Suppressed Spectrometry (TIGRESS) in Canada.

Parçacık ve Gama Işını Dedektörlerini Kullanarak Bir Reaksiyonu Analiz Etmenin Farklı Bir Yöntemi

Öz

25Na içeren radyoaktif izotop ışını, 5MeV/akb enerjide ve maksimum saniyede 3x107 parçacık içerecek şekilde deuterated polyethylene (CD2) hedef üzerine (d,p gama) reaksiyonunu araştırmak üzere gönderilmiştir. Buna rağmen, aynı çarpışmadan kaynaklanan farklı reaksiyon türleri olabileceği için, bunların dikkatlice ayrıştırılması gereklidir. Parçacık ve gama ışını dedektörü olarak, çift taraflı şeridi olan silikon dedektörleri ve yüksek saflıkta germenyum dedektörleri kullanılarak, 26Na çekirdeğinin farklı enerjilerdeki durumları elde edilmiştir. Bu çalışmanın motivasyonu ise, farklı tipteki detektörlerden gelen bilgileri birleştirerek, daha önceden gözlenmemiş yeni verilere nasıl ulaşılabileceğini göstermekdi. Bu çalışma, SHARC ve TIGRESS dedektörlerinin bulunduğu Kanada’da yapılan deneyin bir parçasıdır.
