Emission of fragments in Ca+Ca reactions at 25 MeV/nucleon

the role of application of dynamic assessment approach in improvement of iranian efl writing performance at different language proficiency levels

the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...

metallicity of starburst galaxies in chandra deep field south (cdf-s) , at 0.5

چکیده یکی از پارامترهای اصلی در دنبال کردن تاریخچه ی تشکیل ستاره ها و تحول کهکشان ها، مطالعه ی میزان فراوانی عناصر آن ها است. در این پایان نامه برای مطالعه ی همبستگی میان فراوانی فلزی و جرم ستاره ای کهکشان ها، از داده های طیفی 89 کهکشانِ ستاره زا استفاده شده است. طیف ها توسط طیف نگار فورس2 از میدان ژرف جنوبی چاندرا گرفته شده و جابه جایی به سرخ طیف ها همه بزرگتر از نیم و کوچکتر از یک هستند. جر...

Near-scission emission of intermediate mass fragments in C¿Th at EÕAÄ16 and 22 MeV

Intermediate mass fragments ~IMFS! ~IMF: 3<Z IMF<20) observed in coincidence with two correlated fission fragments following incomplete fusion in C1Th at E/A516 and 22 MeV are investigated. IMFs emitted prior to significant deformation of the fissioning system, as well as IMFs emitted near scission, are distinguished based upon their characteristic kinetic energy and angular distributions. The ...
